But the x-pro from sipphone.com does have the g729 codec included at USD 7.99 price. I have just bought a copy, downloaded and installed it. The g729 codec is also highligted. I could disable all other codecs except g729 and then make a local call. The xlite version from sipphone.com does not have the g729 codec. TSIP softphone: G.729 codec module template. Although G.729 patents may have expired already (20 years have passed for original G.729 ITU, see ITU patent list) or they may even be meaningless in my country (in similar way to FFmpeg from France that uses many patented algorithms) I'm not a lawyer and I'm not willing to include G.729 directly in softphone at the moment. Listen to Ordinary softphone with G.729 codec; Listen to MizuPhone with Ultra WideBand codec; voice recorded with a low-cost sound card (found in most PC's and laptops) Highlights: MizuPhone was the first business class sip softphone with ultra wideband codec. MizuPhone was the first business class sip softphone with file transfer over basic.

Softphone With G729 Codec

IP Office Softphone - Codec selection

The g729 codec is a low bandwidth/high quality codec that’s available as an in-app purchase in Groundwire It can be found in SettingsAdd onsG.729. Acrobits Softphone & Groundwire Tickets. 3cx phone on PC (in general connected via Ethernet, LAN): Codec Priority 1: PCMA. Codec Priority 2: G729. 3cx phone on Smartphones (planned) G7.29. This results in the following codecs chosen for calls: Desktop phone - Desktop phone: G7.22 (G7.11 if concurrent calls HD limit exceeded) Desktop phone - PSTN: PCMA.

IP Office Softphone - Codec selection

Hi guys!
IPO 9.0.4:
I have a collague who sits in Canada. Because his internet connection isn't the best we thought to use only codec g729 for his softphone (where the 9608 sets here in Austria use g711).
Nothing easier than that, I thought and tried to set the codec for the Softphone. But softphone doesn't use a defined extension (e.g. extension 100 for user 100 as normal h323 phones do), IP Office creates a temorary one on login, which will be gone after softphone logs out. It isn't possible to set codecs there anyway (everything is greyed out). I think in earlier days softphone used defined extensions, but anyway...
To get this working (Softphone using g729, 9608s using g711) I thought to set system default to g729 as first choice and at each phone's extension g711 as sole choice. I guess this would work but I don't like the solution very much (Changing the norm every time (new phone) instead of the exception).
Does anybody have an idea to solve this better? Is there somewhere a (hidden) setting to set a specific codec for softphones only?
Thanks in advance for your suggestions.

Although G.729 patents may have expired already (20 years have passed for original G.729 ITU, see ITU patent list) or they may even be meaningless in my country (in similar way to FFmpeg from France that uses many patented algorithms) I'm not a lawyer and I'm not willing to include G.729 directly in softphone at the moment. Other problem is lack of BSD-compatible licensed implementation - creating own directly from ITU specification would not be cheap.

Building tSIP requires proprietary and not too popular these days Turbo C++. Probably no one would want to install it just for single task thus using G.729 in a form of codec module would be recommended. With tSIP 0.1.45 support for DLL modules (in general intended to be same as baresip modules but with dynamic symbol resulution for calls from module to main application) is added.

Build steps

Softphone With G729 Codec Free Download

download and install Code::Blocks, version with MinGW bundled (codeblocks-16.01mingw-setup.exe is the newest one full installer at the moment)
download tSIP source code, extract to folder of your choice; tSIP source contains some necessary header files shared with DLL
extract g729 module code (archive below) to tSIP/baresip/modules (next to e.g. g722 folder), your layout should look like this:
download Deepwalker G.729 module for FreeSWITCH (search for Deepwalker-fs_itu_g729.tar.gz), extract content of g729a_v11 subfolder to same name subfolder in g729 module;
launch Code::Blocks, open g729.cbp project file (opening g729.cbp directly by double clicking might also work)
make sure target is set to 'Release' (unless you want modify/debug project) and hit 'Build'
g729.dll file should be generated in less than a minute. Create /modules/ subfolder for tSIP.exe and copy this DLL there
(*) if you want to force using G.729 disable all codecs in tSIP configuration (only statically linked codecs are visible there), optionally take a look at tSIP log and/or make test call
(*) if you want to disable G.729 - remove dll from /modules/ subfolder or change its extension to other than .dll

(*) - with tSIP 0.1.48 codec management was improved. After adding module dll codec(s) have to be manually enabled (and can be disabled later without removing dll). With drag-and-drop enabled codecs can be ordered according to preferences (prioritized). Still, due to nature of SDP negotiation if you want to force G.729 usage then disabling all other codecs may be the only way.

Source: g729_template.zip (tested with Code::Blocks 16 + MinGW but C::B 13 seems to work also).

Back to tSIP.
