Dear All, I am facing the issue with one of my client, where my Termination is sending 183 with SDP but my UAC is unable to hear any destination country ringback.
However after connecting the calls there is bi-directional media between 2 end users. I never faced this kind of issue earlier. Could anyone please help me to diagnose the issue and what could be the issue for this. *INVITE SDP (from UAC to SBC)* v=0 o=Sonus_UAC 10849 14981 IN IP4 203.176.253.100 s=SIP Media Capabilities c=IN IP4 203.176.253.101 t=0 0 m=audio 9210 RTP/AVP 18 4 8 101 a=rtpmap:18 G729/8000 a=rtpmap:4 G723/8000 a=fmtp:4 annexa=no;bitrate=6.3 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sendrecv a=maxptime:30 * 183 w/SDP from (SBC to UAC)* v=0 o=dasbc11 211356 211357 IN IP4 208.80.45.205 s=sip call c=IN IP4 208.80.45.207 t=0 0 m=audio 38972 RTP/AVP 18 101 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 Thanks, Nitin Kapoor _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
