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" ?!

Hi Guys,
Just qurious.. How intrested are you guys in a very simple transcoder, wich is based on rtpproxy ?

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.

OpenSER does only signaling, so it is not able to transcode. Asterisk, for example, does. Cheers, Daniel On 02/15/07 10:57, tusker keg wrote:

I have a situation I hope you guys will help me out with
I am receiving call from a VOIP peer (SIP Call) and the peer can only send them as G711. I need to redirect to call to another voip peer over the wan and due to bandwidth considerations I need to translate the codec to g729.
Any ideas on how to do this,
Sample config file will be help
