something you can do Daniel ?

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:
http://sourceforge.net/tracker/?atid=743022&group_id=139143&func=br…
Thanks,
Daniel

Both have nothing to do with codecs, which are
