Hi Again Stefano,
Me and Stefan Sayer made a patch to rtpproxy and to nathelper module in
ser, so it changes the sdp, and do transcodeing. It works, but it has a
few bugs in the nathelper code atleast, and it needs atleast a function
to check codecs etc.
but, on the other hand.. we have had a few calls over it, and it seems
to work rather Ok when my nathelper patch does'nt crash ser :-)
So, if anyone is willing, they can proberbly get to adopt the code, and
productify it.
So alittle status on the code:
The code was written for SER trunc about half a year ago. The nathelper
part is written by me, who does'nt do C very much, so that part is very
flacky. but as a proof of concept it works.
There is a need of a function as decribed above that can check what
codecs the UA supports.

Hi,
we would be very interested! :-)
I think it's a great idea but...what do you mean with "very simple" ?!

http://openser.org/cgi-bin/mailman/listinfo/users Hi,
rtpproxy and mediaproxy do media-relaying and OpenSER does SIP routing. Both have nothing
to do with codecs, which are
negotiated end-to-end. So yes, OpenSER and rtpproxy/mediaproxy do support G729 in a sense
that they allow UACs to
communicate with G729. If you want to transcode between codecs (e.g. G711 <-> G729),
you need - as Daniel already said - a
transcoder like Asterisk.

Hello Daniel ,
I'm Also Having the Same doubt on g729 Codec,
I'm using RTPproxy with Nathelper ,
OpenSER and RTP proxy does media signaling when the Call is Established,
My main question is
Is RTP proxy support the G729, with OpenSER,
With out using the Transcoder ( Asterisk ) How can OpenSER signals the G729 Codec.

Hello,
you need a transcoder in the middle. OpenSER does only signaling, so it
is not able to transcode. Asterisk, for example, does.
Cheers,
Daniel
