[OpenSIPS-Users] media proxy - B2BUA(signaling only)

[Bogdan-Andrei Iancu]

Hi Julien,

Just a wild guess - maybe the mediaproxy does not work as you may invoke 
it (request and reply) for different calls (for request on UA_A call and 
for reply on UA_B calls) - afaik, both mediaproxy and rtpproxy use the 
callid in order to bridge the request and reply SDP ports....But because 
of B2BUA, you actually have 2 calls.

So, be sure you do both media setup steps on the same call (only on one 
side of the B2BUA).

Regards,
Bogdan
