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.
could you upload the patches to the tracker? It sounds very useful in
some scenarios. We will have a look and make sure that the patch for
nathelper gets very well integrated in existing code. Here is the link
to the tracker:

Thanks,
Daniel
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,
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.
