Dear Friends, I am facing the problem with one of my customer where first the calls has been connected successfully and then UAC sends the re-invite my SBC sends 488 back to UAC.
When UAC sends the Initial OFFER i had below SDP. (UAC --- SBC) and i can see the "ptime" value is 30 and calls established. v=0 o=Sonus_UAC 16515 29422 IN IP4 209.58.46.49 s=SIP Media Capabilities c=IN IP4 209.58.46.40 t=0 0 m=audio 11516 RTP/AVP 4 18 101 a=rtpmap:4 G723/8000 a=fmtp:4 bitrate=6.3 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=sendrecv a=maxptime:30 Now when UAC sends the re-invite we have below SDP. If you can see in re-invite "ptime" value has been changed.. Is that acceptable? Or you have seen any other thing in SDP. v=0 o=Sonus_UAC 16515 29423 IN IP4 209.58.46.49 s=SIP Media Capabilities c=IN IP4 209.58.46.40 t=0 0 m=audio 11516 RTP/AVP 18 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=sendrecv a=maxptime:20 Could anyone please give some shadow on this. Thanks in Advance.
