VoIP/SIP client (softphone) for Windows

Download the latest release: tSIP_0_3_09_bin.zip (basic version, without video support).

When looking for a SIP and media stack I've spotted libre/librem/baresip from creytiv.com. It has I believe pretty unique combination of simplicity, completeness and most of all permissive BSD-style license allowing commercial and closed-source derivatives.

Quick specification

Note: page is organized in chronological way. This specification refers to latest version.

• portable, small (~8.6MB disk space) Win32 application with settings stored as JSON
• customizable GUI suitable for specialized purposes like kiosk applications
• single account (although multiple instances can run simultaneously)
• single call by default but since version 0.3 able to handle multiple calls with conferencing and attended transfer
• UDP/TCP/TLS signaling transports, RTP/SRTP/ZRTP media
• programmable buttons (similar to many bench phones: Speed dial/BLF/MWI/DTMF/Redial/Blind transfer/Hold/Mute/...)
• BLF with state-based number dialed on click (call transfer, call pickup with BLF)
• presence subscription
• console-only mode (intended to work as additional BLF console / extra sidecar for desk phone)
• click-to-call / "callto" web browser integration / command-line control
• Bellcore-dr1...dr8 ring selection
• call recording (as mono or stereo wave or Opus/OGG files) with separate records browser and call transcribing using whisper.cpp
• RTP streaming (unicast/multicast paging, transmitter only)
• plugin interface for external software/hardware integration and odd functionality
• customizable local and global hotkeys allowing e.g. calling to number copied to clipboard, answer/hangup call without restoring application from tray
• separate audio device selection for input, output, ringing and paging/intercom
• switching audio input (e.g. playing wav file) and output ("speakerphone") devices during call
• auto-answer after time and/or with respect to Call-info answer-after parameter
• Lua scripting - scripts assigned to buttons or events, allowing to implement e.g. SIP originate function
• video support (enabled by compile-time switch) with OpenH264
• BSD license; customizable and brandable without the need of going open source

Console application

Minimal subset (no video support, no codecs besides G.711, just the essentials for voice calls) of libre/librem/baresip as a console application built with Turbo C++ 2006 Explorer. If you're not a Borland products user stay with original source code that can be used with i.e. VC++ 2003.

GUI SIP client

SIP client with graphical user interface built upon re/rem/baresip stack. Initially feature set was limited, currently it is probably one of the most feature rich softphones, especially taking plugins into account. Application is portable and using configuration from a local JSON file, so many instances can be run simultaneously with different configurations.

• Initial release: Version 0.1
  tSIP_0_1_src.7z (435 kB)
  
• 2012.01.11 Minor fixes
  tSIP_0_1_1_bin.7z
  tSIP_0_1_1_src.7z
  • lib project dependencies handled in a better way (#pragma link "re.lib", library search directory changed depending on current build configuration),
  • FIXED: possible Access Violation errors on quit or restart,
  • added missing handling of transport and expires configuration parameters,
  • ignoring incorrect stale=FALSE (treating always as stale=TRUE) parameter put by some other device with SIP/401 message that was causing periodical loss of registration; hopefully this would be only temporary change.
• 2012.01.16 tSIP_0_1_2_bin.7z, tSIP_0_1_2_src.7z
  • re/rem/baresip sources updated to version 0.4,
  • winwave.c: fix for small, non-recurrent memleak,
  • added baresip portaudio module and necessary PortAudio v19/DirectSound statically linked library; PortAudio is now default sound backend, WaveIn/WaveOut is left as an alternative,
  • removed unnecessary parts from displayed call URI.
• 2012.01.28 tSIP_0_1_3_bin.7z, tSIP_0_1_3_src.7z
  • added baresip speex module and required statically linked library,
  • added transmitted and received SIP message logging option,
  • ua_find(): trying to match incoming requests using AOR if matching by Contact fails; matching by Contact only may cause interoperability problems (see Nokia: Problems with incoming VoIP 3.x calls).
• 2012.04.28 tSIP_0_1_4_bin.7z, tSIP_0_1_4_src.7z
  • re/rem/baresip sources updated to version 0.4.1,
  • GUI: added auth username to configuration,
  • GUI: fixed problem with temporary freezing when opening log window after long work time.
• 2012.05.10 tSIP_0_1_5_bin.7z, tSIP_0_1_5_src.7z
  • added baresip gsm module and statically linked gsm library,
  • added module for G.726-32 codec and G.726 code from older SpanDSP version (copyright Sun Microsystems and Steve Underwood, public domain),
  • added codec set configuration (enable/disable particular codecs).
• 2012.07.22 tSIP_0_1_6_bin.7z, tSIP_0_1_6_src.7z
  • added local address setting - equivalent of baresip "sip_listen", may be required when using on machines with more than one network interface to specify interface to bind to.
• 2013.11.20 tSIP_0_1_7_bin.7z, tSIP_0_1_7_src.7z
  • application version that handles multiple accounts and multiple calls was moved to separate branch (mtSIP),
  • updated re (0.4.5), rem (0.4.4), baresip (0.4.6) sources,
  • log window: added "Save to file" to context menu and "Log to file" checkbox (duplicating settings),
  • added re-register button (forcing immediate re-registration),
  • eliminated GUI freezing when application was closing during registration that would fail due to no response from 2nd party,
  • auto-answer with specified SIP code,
  • added (very crude) call history,
  • added redial button,
  • making call: assumed that if sip: prefix is present uri domain does not have to be added (previously: unable to call i.e. sip:192.168.1.11 uri, call function was assuming that domain was not present if "@" in uri was not present).
• 2014.03.19 tSIP_0_1_8_bin.7z, tSIP_0_1_8_src.7z
  
  • moved baresip code into separate static library (mostly to speed up often unnecessarily forced by TC++ whole project rebuilds),
  • dialpad: added A, B, C, D DTMFs,
  • added Flash button (sent as DTMF event),
  • added Hold function,
  • added blind transfer function.
• 2014.05.27 tSIP_0_1_9_bin.7z, tSIP_0_1_9_src.7z
  
  • added Speed Dial / BLF panel (application/dialog-info+xml subscription).
• 2014.06.01 tSIP_0_1_10_bin.7z, tSIP_0_1_10_src.7z
  • FIXED: account configuration: entering password is not required,
  • FIXED: FLASH is no longer displayed as 'R' when dialing,
  • FIXED: inconsistent application state when UA was restarted (configuration changed) during a call,
  • making call with [Enter] in number edit field,
  • auto-repetition for "backspace" button.
• 2014.08.07 tSIP_0_1_11_bin.7z, tSIP_0_1_11_src.7z
  Added Accept header to SUBSCRIBE message. Although it shouldn't be required (see RFC6665, 3.1.3), Asterisk 11.9.0 is dropping these type of message with error: WARNING[14547]: chan_sip.c:27847 handle_request_subscribe: SUBSCRIBE failure: no Accept header: pvt: stateid: -1, laststate: 0, dialogver: 0, subscribecont: '', subscribeuri: ''. Thanks to Barry Mercer for reporting.
• 2014.09.27 tSIP_0_1_12_bin.7z, tSIP_0_1_12_src.7z
  • added WebRTC Acoustic Echo Canceller as static library,
  • AEC selection: none/Speex/WebRTC,
  • fixed audio problem with WaveIn audio input (waveInUnprepareHeader() misorder).
  Earlier versions have acoustic echo canceller (AEC) in a form of Speex AEC disabled due to unsatisfactory results achieved with it. Implementation in this version using WebRTC seems to work much better. In my tests most stable results were achieved when combining WebRTC AEC with WaveIn/WaveOut audio and results varied between computers (perhaps manual delay parameter tuning may be needed) with PortAudio/DirectSound.
  Note: this is local echo canceller - it eliminates echo introduced by local speakerphone-microphone audio path (and heard by our caller), not echo that may be heard from second party.
• 2014.10.03 tSIP_0_1_13_bin.7z, tSIP_0_1_13_src.7z
  • separate audio module selection for audio source, output and output for ringing.
• 2014.10.05 tSIP_0_1_14_bin.7z, tSIP_0_1_14_src.7z
  • crude contact list / phonebook,
  • json-cpp code moved into separate static library,
  • fixed status text when account changed to account without registration,
  • added CALL_STATE_OUTGOING, UA_EVENT_CALL_OUTGOING (feedback before contacting 2nd party on outgoing call),
  • added CALL_EVENT_TRYING, UA_EVENT_CALL_TRYING (info on receiving SIP/100).
• 2014.10.16 tSIP_0_1_15_bin.7z, tSIP_0_1_15_src.7z
  • fixed audio device selection for winwave output (default device was always opened),
  • tray icon, File/Minimize to tray, "X" button minimizes to tray,
  • settings: Start minimized to tray,
  • status text as tray hint,
  • cleanup: Hangup()/CALL_STATE_CLOSED code duplication,
  • simple tray notifier window, related settings added.
• 2014.11.02 tSIP_0_1_16_bin.7z, tSIP_0_1_16_src.7z
  • replaced str_error calls in SIP replies with fixed text (when replying to re-INVITE with image media only invalid message was generated with "Unknown error" followed by empty line),
  • fixed minor built problems: reference to missing module with webrtc, not all projects included in main project group, missing (strangely only with particular TC++ copy installed) mmsystem.h include,
  • fixed: no ring tones when working directory was different than application directory (e.g. when using start softphone01\tSIP.exe from batch file),
  • clearing BLF icon from speed dial panel when BLF subscription is disabled,
  • settings: delay for the auto answer, randomized (for fuzzing purposes) from specified range.
• 2014.11.23 tSIP_0_1_17_bin.7z, tSIP_0_1_17_src.7z
  • fixed audio device enumeration in settings window,
  • GUI scaling (main window),
  • intercom/paging (separate audio output on incoming INVITE with Call-Info with answer-after),
  • winwave: fixed handle leaks (waveInUnprepareHeader called after waveInClose, with invalid dev handle),
  • configurable buttons (in a similar way to e.g. Yealink phones):
    • type (disabled, speed dial, BLF, DTMF, redial, transfer, hold, ...)
    • caption - displayed text
    • basic number (if applicable for selected type)
    • height - allowing customize different buttons size or just fit more buttons in a column
    • top and bottom margins - allowing to insert some space before/after button or just get rid of excessive buttons leaving only few visible (buttons are using flow layout)
    • show/hide image
    • images selection for non-BLF and BLF type buttons; customized images are intended for better representation of information type supplied e.g. with custom asterisk hints
    • note: multiple buttons of the same type can be programmed and their state is synchronized; in case of BLF there is only single subscription to server if multiple buttons with same number are added
  • removed A, B, C, D DTMF keys from main keypad; note: these signs can be programed with DTMF type (programmable) key
  • setting: double width for speed dial.
• 2014.11.29 tSIP_0_1_18_1_bin.7z, tSIP_0_1_18_1_src.7z
  
  • additional configuration for BLF buttons: number dialed when button is pressed can be changed to different than number for subscription and depend on subscribed number state; this can be treated as generalized "Call pickup" function available e.g. on Yealink phones (to get identical behavior mark "early" for override and enter complete number that has to be used to pickup call from other extension on PABX)
  • new button type: unsolicited MWI (displaying number of new and old messages on voice mail); image shown when there are new messages is shared with BLF "early" setting, example images are included - see screenshot
  • new button type: MUTE
• 2014.12.06 tSIP_0_1_19_bin.7z, tSIP_0_1_19_src.7z
  • web browser integration
• 2015.01.04 Version 0.1.21
  • fixed command line execution when other instance was not found (accessing released memory)
  • settings: console-only mode - intended to work as an extra console for desktop phone
  • changed registration expires in default configuration to 0; this disables registration by default - deregistration attempt from nonexistent server (long timeout) is annoying and it's not very likely that default registration server address (i.e. localhost) would match user registrar
  • moved ring initialization to top level project (fixes issue with short ringtone being played even with auto-answer with zero delay)
  • separate ringtones selection for INVITEs with Alert-Info: info=<Bellcore-dr1> header (Bellcore-dr1 ... Bellcore-dr8) and for default ring; note: wav files have to be placed in application directory
  • new function and button type: mute ring
  • settings: action for "X" button in main window: minimize to tray or close
• 2015.01.15 tSIP_0_1_22_bin.7z, tSIP_0_1_22_src.7z
  • FIXED: SIP/500 response was sent since v0.1.21 on missing Alert-Info,
  • new setting for BLF button: action when button is pressed during call:
    • none (= no action, same as in previous version)
    • DTMF dialing with optional prefix to be added (prefix can be PABX transfer code or even "R" for FLASH if PABX supports it)
    • blind transfer using REFER (default)
  • (again) more console columns (up to 5 + 1 "basic") giving up to 55 buttons (up to 75 with reduced button height); minor cleanup to make adding more columns later easier (change EXT_CONSOLE_COLUMNS + add item to combobox in settings window),
  • version info: added file description (presented e.g. in Process Explorer and some firewalls).
• 2015.01.19 tSIP_0_1_23_bin.7z, tSIP_0_1_23_src.7z
  • minor improvements to call history:
    • keeping only user part of URI from incoming call
    • size increased to 1000 entries
    • not skipping entries with duplicated numbers / URIs
    • storing call time
    • displaying call direction and completion
  • settings: shortcuts (local to the application)
    • hide application
    • answer/hangup call
    • equivalent of pressing configurable (console) button; for button ID check caption of button edit window
  • settings: width for console columns
• 2015.01.31 tSIP_0_1_24_bin.7z, tSIP_0_1_24_src.7z
  
  • fixed console-only mode
  • switching to/from console-only mode does not require restart
  • note: you can use 0.0.0.0:XXXX to bind to specific port without entering any specific IP address (and you may need binding to fixed port if you'd like to e.g. make calls using IP address, without registering to any server)
  • log: added timestamp to log entries with SIP sent/received messages
  • global hotkeys (hotkeys that work even when application is hidden); since it may be quite hard to find unique hotkey combinations use them sparingly - my recommendation would be using global hotkeys for show/hide app and answer/hangup and local hotkeys for other actions
• 2015.02.07 tSIP_0_1_25_src.7z
  • build options: instruction set changed to Pentium Pro for all projects and targets
  • TimeCounter.h: time measurement utility for basic testing
  • setting focus to call number edit box on startup and when application is called with global show/hide hotkey (allowing dialing number without using mouse while keeping application hidden normally)
  • hotkeys: new action available: redial (although same effect can be achieved by assigning redial function to one of the speed dial keys and then assigning this button as action)
  • fixed: uninitialized values for new hotkey button (i.e. "global" checkbox often set by default)
  • fixed: halt in global buttons unregister loop
  • contacts: note field added
  • contact note popup window (auto popup on incoming and/or outgoing call if note is not empty and specified option is set); window position and size is stored in configuration
  • new button type: show contact note popup
• 2015.02.18 tSIP_0_1_25_1_bin.7z, tSIP_0_1_25_1_src.7z
  • fixed regression (0.1.25): "Cannot focus disabled or invisible window" exception when starting application minimized to tray
  • Branding.[h|c] - common application name/protocol handler definition to reduce differences between branded and regular version
• 2015.02.28 tSIP_0_1_26_bin.7z, tSIP_0_1_26_src.7z
  • (very basic) call recording
    • settings: on/off switch (all calls are recorder automatically when enabled)
    • writing files to \recordings subdirectory
    • filename contains date, time, direction ("1" for incoming, "0" for outgoing) and 2nd party number/URI encoded in base64
    • output format: WAV, both direction mixed into single channel, PCM 8000sps, 16bit (~55MB per hour)
• 2015.03.04 tSIP_0_1_27_bin.7z, tSIP_0_1_27_src.7z
  • recording can be disabled and hidden altogether (e.g. for legal reasons) without recompiling by opening executable with resource editor and changing "RECORDING_ENABLED" string to any other value; for extra protection from user manipulation Yoda's Protector or similar tool may be used
  • settings window can be closed with Esc key
  • new hotkey action type: call to number from clipboard (select number in web browser, hit Ctrl+C and than assigned global shortcut to call; I'd suggest using global hotkey with Ctrl, e.g. Ctrl + Browser Forward Key for this purpose)
  • fixed: global hotkeys not working with Win Vista and earlier systems because of MOD_NOREPEAT flag used; added OS detection and app-based antirepeat (with 1s timeout) for systems older than Win7
  • settings: restore minimized / bring main window to front on incoming call
  • settings: show tray notifier window on outgoing call (e.g. when using global hotkeys)
• 2015.04.11 tSIP_0_1_28_bin.7z, tSIP_0_1_28_src.7z
  • DLL plugin system for interfacing external devices; implemented interface for EX-03 USB phone (aka @phone); most likely compatible also with EX-02 and few other similar devices
  • FIXED: incorrect parameter (branding module not used) in protocol handler links
  • protocol handler: added "ANSWER" parameter (next to "HANGUP")
• 2015.04.16 tSIP_0_1_29_bin.7z, tSIP_0_1_29_src.7z
  • FIXED: global hotkey unregistration and phone interface shutdown with "X" button when this button was configured to minimize to tray; added TfrmMain::Finalize()
• 2015.05.04 RingAction.7z: mini-plugin that executes hidden command line shell (cmd.exe) with specified parameter (command) when softphone starts ringing. In my particular usage this is intended to stop media player (that is SMplayer) on incoming call. SMplayer can be controlled with -send-command option:

  D:\progs\smplayer\smplayer -send-action play && D:\progs\smplayer\smplayer -send-action pause
  		

  Each time both play and pause commands are sent to handle both cases when SMplayer is playing or is not playing at the moment (pause command itself works as play/pause switch). Command to execute is specified with JSON .cfg file, using JSON editor might help with proper escaping for complex command lines.
• 2015.05.10 RingPCSpeaker.7z: mini-plugin: ringing using PC speaker (with WinAPI Beep() - does not work as expected with 64-bit windows version as it is routed to default sound device instead of activating physical PC speaker as with 32-bit windows).
• 2015.05.31 tSIP_0_1_30_bin.7z, tSIP_0_1_30_src.7z
  • FIXED: regression: call history not saved on system shutdown (WM_ENDSESSION handler)
  • fixed handling of missing plugin DLL
  • contacts: CSV import
    
• 2015.06.06 tSIP_0_1_31_bin.7z, tSIP_0_1_31_src.7z
  • contact note popup and contact node editor: URLs are highlighted and opened in default browser when clicked
  • recordings: custom directory can be set for output (e.g. located on shared network drive)
  • added exe location to "About" window (click to open application directory)
  • call duration is displayed in "Connected" state
• 2015.07.04 tSIP_0_1_33_bin.7z, tSIP_0_1_33_src.7z
  • recording: encoding of number/URI in wav file name changed to filesystems-safe version of base64 alphabet
  • new button type: HTTP query - open specified URL (e.g. search engine or web-based corporate database) with number from last (or current) incoming call passed as parameter; by default google is used
  • settings: added RTP/RTCP local port range selection
• 2015.07.06 RecordViewer - simple browser for recorder calls
• 2015.08.08 tSIP_0_1_34_bin.7z, tSIP_0_1_34_src.7z
  • added SIP presence subscription
• 2015.08.15 tSIP_0_1_35_bin.7z, tSIP_0_1_35_src.7z
  • presence button shares more settings with BLF: when pressed in-call works as blind transfer or DTMF sequence with optional prefix for attended transfer
  • new button type: UNREGISTER
  • recording: option to record calls in stereo, that is each call side into separate wave file channel; useful e.g. for echo and delay testing; note: this doubles resulting file size (effectively 256kbps, 110MB/h)
• 2015.08.28 tSIP_0_1_36_bin.7z, tSIP_0_1_36_src.7z
  • fixed regression (0.1.35) in single channel call recording
  • added baresip aufile (wave file as sound source) adapted to Win32
    • presented as another (next to WaveIO and Portaudio) sound module for audio input
    • requires S16LE, 1ch, 8kSps wave file, located in application directory
    • call is disconnected at the end of file
    • allows making call with no system sound device (MB with jack auto detection)
    • poor man's voicemail (when combining announcement with silence at the end with call recording and auto answer)
  • ACTION_SHOWWINDOW (SHOWWINDOW command line parameter) - bring application from tray
  • new setting in "General" page: single instance (bring previous instance to front if already running); uses SHOWWINDOW action and same mechanism as click-to-call
• 2015.09.02 tSIP_0_1_36_1_bin.7z
  • FIXED: problem with ring and wave source files selection (case sensitivity)
• 2015.09.11 tSIP_0_1_36_2_bin.7z
  • FIXED: in default configuration input device type was set to wave file (while file itself was not selected resulting in immediate call drop)
  • FIXED: NUL (0) characters were written in log file at the end of every line; strangely neither notepad nor notepad++ care about it
• 2015.10.24 Plugin for running simple scripts using Lua
• 2015.12.05 tSIP_0_1_37_bin.7z, tSIP_0_1_37_src.7z
  • new button type: execute arbitrary application; may be used to run RecordViewer or e.g. notepad passing number from last call as part of command line arguments or file name to open/edit
• 2016.01.24 tSIP_0_1_38_1_bin.7z, tSIP_0_1_38_1_src.7z
  • new function: RTP streaming (paging, sender only)
    • new button type
    • target address can be specified as unicast or multicast (e.g. 192.168.1.10:4000)
    • for each button that starts streaming separate wave file to stream can be specified; if wave file is not specified then default audio source from configuration (e.g. microphone) is used
    • note: at the moment only G.711a can be used for streaming and enabling G.711a/u in configuration is required
    • extended plugin interface while keeping it backward compatible (optional functions to be exported by dlls)
      • SetPagingTxCallback - set function to be called by dll to start paging
      • SetPagingTxState - inform dll about started/stopped paging
      • ClearDial - clear number edit content
  • account settings: added outbound proxy (equals to baresip outbound1 parameter for account but by convention - same as with SIP server - sip: prefix should not be included)
  • minor cleanup for account configuration window with separating
    • basic settings (server, UDP/TCP, user, password and registration Expires/disabling)
    • from optional extra settings
• 2016.02.02 tSIP_0_1_39_bin.7z, tSIP_0_1_39_src.7z
  • FIXED regression (0.1.34): not working MWI
  • handling NOTIFY with "Event: talk" (answering call remotely, intended for interoperability with some CRM using asterisk AMI to control softphone), new setting in "Call" tab
• 2016.02.13 tSIP_0_1_40_bin.7z, tSIP_0_1_40_src.7z
  
  • configuration of programmable buttons moved to separate file (tSIP_buttons.json) to reduce main configuration file grow and possibly make it easier to share keys configuration between users or application instances
  • if new keys config file is not found application will try to create it by moving settings from main config file; if earlier application version would be started next (downgrade) it would not find new settings so manual JSON merge may be needed
  • maximum number of sidecar columns increased from 5 to 12 giving up to 132 programmable buttons (with reduced buttons height: up to 180); note that to use full 12 columns with default column width screen with 1440px width would be required
  • FIXED: problem with inconsistent sidecar columns order when switching number of columns without restart
  • added "Reset all" button to edit window for programmable buttons
  • minor changes to programmable button edit window: separated visual settings
  • custom background colors (including system colors) can be assigned for programmable buttons (visual grouping for BLF)
  • FIXED: if programmable button with type = Disabled was clicked there was log line: "Unhandled BTN type = some_big_number"
  • SpeedDial button type shares with BLF and Presence setting for action when pressed during call (DTMF or transfer)
• 2016.02.24 tSIP_0_1_41_bin.7z, tSIP_0_1_41_src.7z
  • FIXED: with message logging: message body was not displayed (only headers) for incoming messages
  • added action (= new possible keyboard shortcut): toggle sidecar
  • modified settings window (categories tree on the left side)
  • separated network settings (bind address, RTP ports)
  • Polycom-style Call-Info: Answer-After=X in incoming invite is recognized (in addition to previous Call-Info: <uri>;answer-after=X)
  • new account setting, "answer any"; if enabled account is treated as "local account" and used to process any incoming message that would be otherwise answered with SIP/404 if account for which it was intended was not found; intended to allow using softphone for some testing purposes like simulating PABX that is processing any call
• 2016.03.12 tSIP_0_1_42_bin.7z, tSIP_0_1_42_src.7z
  • [Display Name] is used as description line if number was not found in phonebook
  • new setting: show only user part (if present) of URI as CLIP
  • Contacts: filter matches also phone numbers / URIs
  • added filtering to call history
  • call history stores display names from incoming INVITEs
  • call history displays contact names if available, then display names and finally numbers if names are empty
  • FIXED: memory leak: contact_any
  • added G.722 codec; note: WebRTC AEC is currently disabled for 16kHz sampling
• 2016.05.03 tSIP_0_1_43_bin.zip, tSIP_0_1_43_src.7z
  • added jitter buffer configuration; use only if needed, e.g. with extreme cases of VoIP over multiple layers of VPN or Tor
  • new button type: script
• 2016.05.13 tSIP_0_1_44_bin.zip, tSIP_0_1_44_src.7z
  • quick fix for problem with passwords containing "@" (problem with AOR decoding solved by passing password separately when creating account)
  • codec selection (PCMA/PCMU/G.722) for paging; make sure that selected codec is enabled in configuration
  • added (optional) network adapter selection that may help with other than expected SDP c line address if there are multiple network adapters installed: adapter list dump in log on startup, new setting in "Network" tab - use full adapter ID, on windows with curly brackets ("{012345678-0123-0123-0123-ABCDEF012345678}")
• 2016.05.22 tSIP_0_1_45_bin.zip, tSIP_0_1_45_src.7z

  • call history popup menu:
    • add/edit contact
    • copy number to clipboard
    • HTTP query (same as with programmable button, opening browser searching with google for number by default)
  • contact editor can be closed using Esc
  • 3 numbers per contact; first nonempty used as default when calling using double click, use popup menu to call using specific number
  • added "Company" to contacts
  • new setting: Contacts: Filter using contact note
  • [Enter] in contacts and history filters moves focus to list
• 2016.05.29 tSIP_0_1_46_bin.zip, tSIP_0_1_46_src.7z

  • button labels are transparent and on front thus button image can be used as sort of background
  • added background image selection for dialpad
  • turned off TabStop for dialpad 0...9*# buttons
  • FIXED: memory leak when restarting stack (i.e. changing configuration) or closing application while paging is running
• 2016.06.02 tSIP_0_1_46_3_bin.zip, tSIP_0_1_46_3_src.7z
  • branding: application name and default application protocol (for "click-to-call") can be changed by editing resources
  • FIXED: for HTTP query function full SIP URI (not number) from current incoming call was used
  • additional setting for HTTP query function: starting automatically on incoming call or when incoming call is accepted
• 2016.06.22 tSIP_0_1_47_bin.zip, tSIP_0_1_47_src.7z
  • plugin interface: added GetNumberDescription() function (get phone number description from phone book or possibly other future data bank)
  • text-to-speech plugin (talking ringtone)
• 2016.08.24 URL-hit plugin (silently sending HTTP GET request on incoming call)
• 2016.09.03 tSIP_0_1_48_bin.zip, tSIP_0_1_48_src.7z
  • new setting in "General" tab: "Do not beep when using [Enter] in main window to dial or transfer call" - this beep was unintentional but I guess someone might get used to it as a confirmation signal
  • new setting: "History"/"Do not store history to file"
  • [BREAKING] codecs settings from previous version are not preserved; PCMU + PCMA are set as default
  • [BREAKING] codecs from dynamic modules (i.e. G.729) are not enabled by default after loading module
  • new, "correct" (as intended in baresip) way of configuring audio codecs, allowing independently enable/disable codecs if there are multiple codecs registered from single module and prioritize enabled codecs
  • codecs settings are now associated with account, although since number of accounts is limited to 1 at the moment - separate "Codecs" tab in settings is kept
  • codec selection for RTP streaming no longer requires separately enabling specified codec in configuration
  • added L16 codec (unchanged baresip module)
  • added L16/44100 to codec selection for RTP streaming; note that with default 20ms ptime these frames would be fragmented
  • added ptime setting to RTP paging
  • RTP timestamps are starting from random value and few other minor fixes from re/rem/baresip
• 2016.10.16 tSIP_0_1_49_bin.zip, tSIP_0_1_49_src.7z
  • new settings in "General" page: custom main icon file (.ico) and custom tray icon image for unanswered calls notification (.bmp, 16x16), both from /img/ subdirectory; this is intended to help to distinguish multiple application instances (possibly using each instance for separate account) running simultaneously
  • background image can be assigned to tray notifier
  • tray notifier settings moved to separate page
  • new settings: "Hide settings" that may be used to protect configuration from end user, in particular if combined with restricting write rights for main configuration file

  • new button types: switching audio source and audio output during call ("speakerphone")
• 2016.11.19 tSIP_0_1_52_bin.zip, tSIP_0_1_52_src.7z
  • included speex audio preprocessor module from baresip (i.e. speex-based denoise for microphone path)
  • settings: AEC card renamed to "Audio Processing", including AEC and audio preprocessor settings
  • adding audio filters to chain continues if filter installation fails for one of the filters (WebRTC EC supports only 8kHz codecs at the moment; if e.g. G.722 was used with WebRTC EC then recording was not running)
  • no onmouseover for programmable buttons (looking bad on touch screen when mouse cursor is not visible and button is still down), replaced with onmouseup/onmousedown
  • no focus for Call/Answer and Hangup buttons; assumption: local hotkey would be better way to terminate call than tab-cycling
  • settings: disabling context menu for speed dial panels / programmable keys in order to avoid accidental editing when using with touch screen
  • added L16/48000 to codecs set
  • settings: logging: log file flushing (disabled by default to reduce disk activity)

  • settings: added button to refresh DLL plugin list
• 2016.11.26 tSIP_0_1_53_bin.zip, tSIP_0_1_53_src.7z
  • FIXED: division by zero in speex audio preprocessor
  • audio source switching works also with RTP streaming (paging)
  • Lua scripting (integrated):
    • scripts can be executed on events (on call state change, on streaming state change - previously only when button was clicked)
    • added new setting page to assign event scripts
    • ScriptExec: context map for multiple scripts running simultaneously
    • added function SwitchAudioSource (e.g. SwitchAudioSource("aufile", "test.wav"))
    • added function SendDtmf (e.g. SendDtmf("1234*#))
    • added function BlindTransfer (e.g. BlindTransfer("123"))

    • added function IsCallIncoming()
    • added function GetCallPeer() (returning either caller or called number)
    • added function GetStreamingState() (returning int as in Callback::paging_tx_state_e enum)
    • FIXED: added missing Sleep(milliseconds) function
    • added function set to pass variables (states) between script(s) executions:
      • SetVariable("name", "value")
      • value, isset = GetVariable("name") (returning 2 variables, isset == 0 if variable with that name is not set)
      • ClearVariable("name")
      • ClearAllVariables()
    • added GetInitialCallTarget() and SetInitialCallTarget(number) functions allowing to override number dialed by the user and use softphone for call origination
  • settings/Speed Dial: option to ignore presence note (text from server displayed as second line)
• 2016.12.03 tSIP_0_1_54_bin.zip, tSIP_0_1_54_src.7z

• 2017.01.06 tSIP_0_1_55_bin.zip, tSIP_0_1_55_src.7z
  • added option to specify custom User-Agent ("General" page)
  • Lua scripting: added GetRegistrationState() (returning values as in Callback::reg_state_e)
  • Lua scripting: added SetTrayIcon("fileFromImgSubdir.bmp"); on my PC it seems to require 8-bit bmp files for correct transparency handling
    • note: after first function run tSIP stops updating tray icon on its own (regular icon or unanswered call/MWI notification icon)
  • Lua scripting: added "on registration state" script
  • Lua: changed path search order to avoid CodeGuard problems in debug build
  • plugin interface: plugins can now set script variables
  • Lua scripting: added "Answer()" function
  • Lua scripting: added "MessageBox" function - direct equivalent of WinAPI function with same name but with window handle parameter skipped
• 2017.01.16 GetIdleTime.zip - plugin that sets "InputIdleTime" variable for Lua scripts to number of seconds there is no user activity (mouse, keyboard)
• 2017.01.29 tSIP_0_1_56_bin.zip, tSIP_0_1_56_src.7z
  • Lua:

    • added PluginSendMessageText(dllName, text) - method for passing data/control from script to plugin
    • added srcType, srcTypeIsSet = GetExecSourceType() and srcId, srcIdIsSet = GetExecSourceId(): function set that allows reading execution context (i.e. how the script was started, id of the button that script was associated to); this allows using same script file for multiple buttons
    • added InputQuery, allowing to take text input from the user, direct equivalent of VCL function with same name: text, isAccepted = InputQuery(caption, prompt, defaultText)
    • added GetRecordFile() function (returning name of call recording file, empty string if there is no recording); valid after call is established (recording started), cleared on new call, intended to be used mostly at CALL_STATE_CLOSED state
  • added command line APP_QUIT action (can be used as "tsip /tsip=APP_QUIT" from command line or from browser through tsip:APP_QUIT link); this action causes previous application instance to quit and is intended to help with provisioning based on swapping configuration files with downloaded ones (it should be done when application is not running, otherwise configuration file would be overwritten)
  • "Number" label and edit are not displayed when editing "Script" button
• 2017.01.29 CommState plugin - using cheap USB-UART converter as physical interface (GPIO: 2 outputs, 4 inputs available) for softphone.
• 2017.02.25 tSIP_0_1_56_1_bin.zip: changes for video doorphone function using RTSP network camera
  • Lua updated to version 5.3.4 (support for integers and bitwise operators)
  • Lua: added "on BLF (dialog-info) state" event script; numeric ID of the contact that changed state is passed through GetExecSourceId()
  • Lua: added function returning phone number and BLF state for specified contact ID (to be used inside "on BLF state" event script): number, state = GetBlfState(contactId)
  • Lua: added "tsip_winapi" built-in module, intended to hold some functions corresponding directly to Windows API and act as namespace; this module need to be imported with "require" and included functions are not put into global table directly
    • FindWindow
    • SendMessage
    • MessageBox (duplicating same function in global namespace at the moment)
    • Beep (duplicating same function in global namespace at the moment)
• 2017.03.03 tSIP_0_1_56_2_bin.zip
  • added option to start recording in call progress state, that is recording early media (ringback or other announcements from operators before call is connected or if call cannot be connected)
• 2017.03.26 tSIP_0_1_57_bin.zip, tSIP_0_1_57_src.7z
  • new setting, replacing option added in 0.1.56.2 (breaking compatibility): recording start can be set to manual (using Lua script), on call confirmed or on call progress
  • Lua: added function to manually start call recording (if not started automatically): status = RecordStart(filename, channels), where filename = full path and name for record file to create, channels (1 or 2) = mono or stereo (independent channels for call parties) recording
  • Lua: added GetExeName() function, returning full path and application exe name
  • Lua: added GetRecordingState() function, allowing to check if recording is running; might be used if few buttons / scripts able to start recording are defined
• 2017.04.08 tSIP_0_1_58_bin.zip, tSIP_0_1_58_src.7z
  • added ptime configuration (Account tab, as in baresip); changing ptime to 10 is required to make L16/44100 call with pjsip/pjsua on the other side, otherwise there would PJ_ASSERT_RETURN in pjsip l16 encoder
  • Lua: added ForceDirectories(dir) function, same as VCL function but returning 0 on success - to be used before RecordStart() if target directory does not exist yet; requires fully-qualified path, usage: ForceDirectories("D:\\test\\test123")
  • button edit window can be closed using Esc
  • dial buttons, Dialpad/Contacts/History tabs and sidecar open buttons no longer hold the focus (thus focus is always in number edit field allowing using keyboard for dialing and DTMFs all the time)
  • digits entered in number edit during call are generating DTMFs
  • removed trailing newline from text returned by strerror()
  • fixed "Unknown error" log entries after e.g. normal call clearing by second party, added some more descriptive messages
  • reason for registration failure (e.g. 404 Not Found) is shown in status bar (might not fit with long register server name but should be visible if sidecar is open)
  • added "on dial" script, running when user presses one of dialpad keys or is editing main number with keyboard; purpose: generating local audio feedback for dialed digits and DTMFs
• 2017.06.16 tSIP_0_1_59_bin.zip, tSIP_0_1_59_src.7z
  • Lua: added GetCallInitialRxInvite() function, returning full text of first incoming INVITE of incoming call; allows to extract and process custom header lines from "on call state" script, e.g. using Remote-Party-ID to show extra CLIP on one of the buttons
  • Lua: added function description = GetContactName(number) to get contact description
  • settings: added option to force "Contact" user (instead of default random looking hex string)
  • Lua: added GetRxDtmf() function, returning single DTMF sign (or empty string) from reception queue; sign is removed from queue
  • added software volume control for both directions
• 2017.08.27 tSIP_0_1_59_4_bin.zip
  • FIXED: inconsistent application state when handling incoming REFER (call being transferred)
  • added simplified handler for out-of-dialog REFER - this is supposed to work with ANVEO CTI; as this seems little dangerous this is opt-in feature with new settings in "Calls" tab added; note: depending on setup using "Answer any" account option might be required
  • added kiosk mode ("General" tab, later moved to "Locking" tab)
  • added new button types: show settings (blocked if "Hide settings" is used), minimize, show log and exit
  • increased max value allowed for GUI scaling setting to 500%
  • fixed scaling for phonebook and call history list columns width
  • added "Hide mouse cursor" option ("General" tab)
  • added option to set 2 caption lines for programmable buttons, e.g. description + number for BLF button
• 2017.10.11 tSIP_0_1_60_2_bin.zip, tSIP_0_1_60_2_src.7z
  • added separate audio output device selection for ring (incoming call)
  • application version is stored in configuration to help with seamless upgrade (now: copying alert sound device to ring sound device for older version)
• 2017.11.01 tSIP_0_1_60_3_bin.zip
  • added "nullaudio" input (generating silence) and output (discarding samples) audio device; intended to be used on machines with no audio I/O, e.g. with no microphone connected and autosensing jack, virtual machines or when running as service
• 2017.11.12 tSIP_0_1_60_4_bin.zip
  • added "Display"/"Decode Display Name (UTF) to local (ANSI) code page" parameter
• 2017.12.23 tSIP_0_1_61_bin.zip, tSIP_0_1_61_src.7z

  • Settings/Calls: custom/extra header lines can be added to outgoing INVITEs (e.g. Call-Info with answer-after or Answer-After to make second party answer call automatically)
• 2018.04.06 tSIP_0_1_62_bin.zip, tSIP_0_1_62_src.7z
  • removed "tool" line from SDP - suspected to be causing "488 SDP Parameter Error In SIP Request" error when calling using t-mobile.de operator
  • settings: added GUI scaling for tray notifier window
  • added Lua ShowTrayNotifier(description, uri, incoming) function (mainly for testing)
  • neither Answer nor Hangup button is active by default in tray notifier window
  • FIXED: bug in limiting tray notifier window position resulting in not restoring previous position if notifier was near the screen right/down edge
  • interoperability (supervoip.pl, some other German operator): using username as default contact name if contact name is empty instead of semi-random contact name based on memory address
  • "level" label in settings disabled for audio preprocessing
  • added hints for volume reset buttons
  • settings window moved from desktop center to screen center position
  • added Settings/Delete call history menu item (deleting immediately history file content and clearing items from dial combobox)
  • Log and "About" windows can be closed with Esc
  • if call is closed from reason other than normal disconnection - call state label displays reason (e.g. "488 Not Acceptable Here", "480 Temporarily Unavailable") for 8 seconds
• 2018.05.19 tSIP_0_1_62_4_bin.zip
  • added options to hide "View" and "Help" menu (limiting access for the operator together with option to hide settings menu)
  • new command line option: PROGRAMMABLE_BTN_xxx (i.e. "tSIP.exe /tsip=PROGRAMMABLE_BTN_023") - simulating programmable button with ID = xxx (0...100+) being pressed
  • added Lua GetUserName() function, returning user name from configuration - intended to be used to differentiate instances, e.g. fetch list of numbers to call from shared folder with path depending on user name / login
  • FIXED: due to hazard between callback and control queues ring audio might be started after call ended (for calls with CANCEL immediately after INVITE) and not stopped; forcing ring stop on end of call event
  • new settings: "Show main form when answering call" and "Hide tray notifier when answering call"
  • added "General (2)" settings tab
• 2018.07.21 tSIP_0_1_63_bin.zip, tSIP_0_1_63_src.7z
  • Lua: added ProgrammableButtonClick(buttonId) function - simulating clicking on specified button
  • numeric code is added to text (quite often meaningless "Unknown error") generated by strerror
  • registration client: reduced "failwait" saturation time, i.e. maximum time to retry registration from 1800s to 300s (time is randomized and increases exponentially up to this limit)
  • subscription client: removed RESUB_FAILC_MAX limit, added "failwait" similar to registration with 900s limit
  Side note: last "big" Windows 10 update, version 1803 had blocked microphone access without any warning. Apparently "Privacy" / application access to microphone had to be modified.
• 2018.11.12 tSIP_0_1_64_bin.zip, source: tSIP-0.1.64.zip
  • added "logrotate" mechanism; configuration: number of old files to keep (0...5)
  • added queues as new mechanism for connecting scripts and plugins (similar to variables)
  • added Lua FindWindowByCaptionAndExeName(caption, exeName) function
  • added sxmlc library source to re
  • BLF buttons can now show remote identity and call direction (number calling / number called) as 2nd line (opt-out)
    
    This feature seems to be supported by FreeSWITCH and with some issues by FreePBX

  • FIXED: (repeated) delayed auto-answer on answer error
  • added options to set custom application title and main form caption
  • added speex resampler to aufile (wave file) audio input module

      • switching between cameras or camera/video file/colorbar generator
      • might be used for video "mute" function, switching to e.g. animated colorbar generator
      • this button type would be visible also in "audio only" build, but would not take effect
    • new Lua function: SwitchVideoSource(module, device)
    • FFmpeg avformat module can be also used as audio input, adding support for e.g.:

  • contacts: locale-aware comparing/sorting using AnsiCompareIC (e.g. L and Ł should be next to each other)
  • winwave2 is now the default audio input module (due to winwave issue with detaching audio device while this device is in use)
  • default configuration: RTP timeout is now enabled with 300 s time
  • incoming call: tSIP now responds with 488 instead of accepting "silent" call when there are no common codecs

Note: tSIP version with video support requires openh264.dll that needs to be downloaded separately from Cisco page due to licensing reasons. Download openh264-2.3.1-win32.dll.bz2 and extract it (using e.g. 7-zip), rename openh264-2.3.1-win32.dll to openh264.dll and put it next to application executable.

Latest compilation (exe only, to be replaced in regular release) may be often found here.
