HI Peter, First of all thanks for the reply. But I think you have misunderstood the problem. Firstly you can read the problem in previous mail. Actually I was expecting the RTP of called and callee which comes from CISCO Call manager from one port. But unfortunately when call is established between the callee and caller then Call Manger sends the RTP of caller and RTP of callee on different ports. As I was receiving the SDP from call manager with only one media line and one port with sendrecv parameter. That is why my recorder listens all RTP on this port and misses the RTP sent by call manager on the port+2. Call Manger is not mixing the Audio from caller and callee and sending it on one port. Now I have devised a design to resolve this problem. I am adding the two media lines in the SDP for audio RTP/AVP exchange. This SDP I will send with 200 OK to the Call Manager. Then I hope the Call Manager will reply with 2 media lines in the SDP in ACK from it. And two RTP media streams will establish in a call session. The I will try to receive the port of both the RTP streams and add all the media in the conference bridge of the call. From this conference Bridge I am recording so I hope that I will be able to record the two way audio. But this is an raw idea. If any body have more good idea to cure this problem, he is welcome to put his suggestions. Thanks in advance .....
