Re: [Users] Need urgent help/pointers reg. Mediaproxy

I had posted the following a few days ago and received no response. Can someone please help! Hello,I have the following setup: UA<->NAT<-->SER/MediaProxy<->Prepaid(B2BUA)<-->PSTNGW | IVR Nat'd user calls a number that is forwarded (t_relay) to Prepaid and the user is prompted for PIN#/Destination Phone# and all works fine. Mediaproxy is invoked and a mediaproxy port# (35774) is assigned during the whole process. Once the user enters the destination number, the Prepaid forwards the call to the PSTNGW and the PSTN phone rings (Call signalling working fine). When the PSTN phone is answered, no media can be heard!!! I did some investigation and here is what is happening: Once the user enters the destination# to dial, The Prepaid/B2BUA does two things: 1) Sends a re-invite to put the UA on hold. 2) Sends an INVITE to the PSTN GW and retrieves the SDP from the response from PSTN GW 3) Sends a second-reinvite to the UA via SER with the SDP info of the PSTNGW 4) SER invokes the mediaproxy (since it is reinvite) and assigns the SAME MEDIAPROXY PORT# as earlier on when the media was flowing fine (SDP has audio port# 35774) 5) SER forwards the re-INVITE TO UA 6) UA responds with a 200 OK and sends 200 OK to SER. SER agains invokes mediaproxy and assigns the SAME MEDIAPROXY PORT# (audio port 35774) and forwards the response to Prepaid (which sends it to PSTNGW). I checked on Cisco PSTNGW that it is creating a session with the mediaproxy (port:35774). BUT NO AUDIO CAN BE HEARD IN ANY DIRECTION. Can anyone please help? Is this a mediaproxy issue that when reinvites are sent and mediaproxy is invoked multiple times, issues arise? I am running the latest mediaproxy version. ------------------------------------------------------------------------ Have a question? Yahoo! Canada Answers. Go to *Yahoo!
