Android SIP stack - what to use? [closed]

Answer 1

As a fact, no sip stack will give you support for any specific codec. Codec integration always manual as like a plug in.

There is some open-source sip based projects as like csipsimple which has G729 codec integrated . If you study how they have added the codec then you will own able to add any codec in any other sip based frameworks.

Answer 2

Although I have never tried this sdk for mobile development (but I can confirm its performance in the field of Windows VoIP SIP applications), I think this android voip client example can be also a possible alternative to the previously mentioned Android SIP stacks.

Answer 3

I would recommend also Doubango. It supports G729 as you would like, and there's an example project you can look into, which uses the framework - ImsDroid - there's a lot of features already provided by ImsDroid and the source code is open.

Answer 4

PJSIP is highly recommended. You can look at CsipSimple which is an opensource Android phone using PJSIP and a good place to start. PJSIP supports a number of codecs including G.729 and speex, has small memory foot print and has extensive documentation.

Answer 5

I had to build a SIP app for work, currently we are using Linphone which can be found here https://github.com/BelledonneCommunications/linphone-android

It provides a ton of features from VOIP, Chat (text) Video Calls, remote provisioning, as well of a slew of codecs including G729. It does require compiling its C files to java and it takes a little bit for trying to get that to work. This can be done on Windows though it is a fair bit more work and you're better off to use Linux to this.
