Dear Mamadou:

Thanks for your help in the previous thread. I did as your instruction, now I met new problem.

I add G729 codec to webrtc2sip follow these steps, the system works. However there is still problrm. When I make a call between a mobile phone and sipml5 client, the speech I heard from sipml5 (audio stream from IMS to sipml5) is mixed with noise, the speech I heard from mobile phone (audio stream from sipml5 to IMS) is quite clear.

What's the reason of this phenomenon? Is the decode part of G729 which I downloaded defective? If so, is there a better libG729 abtainable?

1/ download G729 source code from https://github.com/winer632/g729
2/ Configure webrtc2sip using "--with-g729"

3/ At the end of the configure check that you've g729 in the list of codecs. If not, check config.log to see what went wong
4/ Modify your config.xml to include g729 in the list of codecs
5/ Please stop sending the same question again and again. And duplicating threads

6/ change this attribute to yes <enable-media-coder>yes</enable-media-coder>.

G729 requires a license. Do you have one? We're distributing G.729 for experimental purposes only as allowed by the license terms and we don't provide support. So, I can't help more.

The implementation to use is at https://github.com/DoubangoTelecom/g729
