Varun, ?I am not sure how the recording system interfaces to your call manager. One possibility is to have the call manager always invite the recording system as an additional party(3rd) for each call as a receive only party. The caller manager would conference the 3(or more) parties and send the mix of the other 2(or more) parties to the recording system who would simply record it to a file. PJSIP has the recorder API already. Since the recording system is receive only, it remains silent and the other parties hear nothing from it. ? --- On Fri, 9/30/11, varun pratapsingh <varunps2003 at gmail.com> wrote: From: varun pratapsingh <varunps2003@xxxxxxxxx> Subject: How to record two RTP Streams coming in one call media session To: "pjsip list" <pjsip at lists.pjsip.org> Date: Friday, September 30, 2011, 3:31 AM HI All, I am developing recording system which works with call manager. When this call manager calls this recording system with INVITE it replies with 200 OK and set ups a call session. Now when session is established between call manager and recording system. The call manager sends two RTP streams in one call session one on port x and other on x+2. My recording system don't send any RTP stream to call manager. Now the I have to mix both the RTP sessions coming from the call manager and record them. So when I am using the API with the following params : pjmedia_conf_connect(pjsua_var.mconf, call_info.conf_slot, recorder_port, 0) Only one RTP session is recorded. Actually the two RTP streams coming from call manager are two side audio conversation. One side audio conversation is on one RTP stream. So we have to actually mix and record them so as to record the actual bidirectional call conversation. So the problem is that only one RTP stream gets recorded and hence in recorded wav file we listen only one side audio. Please help me in resolving this problem. Any help is highly appreciated.
