FW: [Serusers] How to change Mediaproxy codec g-711a to g-729 or g-723 - sr-users

21 Jun 2006

As far as I know mediaproxy does just that, it proxies the call but doesn't
change the codec so if it comes in g729 it goes out the same way.
It doesn't do transcoding. Most of my calls are g729 and you can see these
calls by doing a sessions.py in the mediaproxy server

How about making clients change the default codec to smth else?

 Hi,

 In my understanding, you can't configure media proxy for g729 as it won't
 support g729 codec. It is a patented codec and SER media proxy as well as
 SEMS supports only the patent free codecs like g711a/u or iLBC, etc.  As a
 result of this you will get some choppy sound only if you use g729.  So I
 feel, you have to modify the code in order to incorporate g729 with media
 proxy.

 Regards,

 Benjamin.

 grandstream phone to use only g-729 but  mediaproxy is showing session in
