Hi, I have a weird problem where on certain calls when someone tries to leave a recorded message the call hangs up exactly 60 seconds after the start of the recording. The recordFile is sending the stream to icecast using a shout: address in MP3 format. I've done a line by line compare of a successful call and one where the recording fails and the issue seems to be with the remote SDP. RECORDING SUCCEEDS WHEN SDP IS.. v=0 o=root 1060 1060 IN IP4 77.240.60.33 s=session c=IN IP4 77.240.60.33 t=0 0 m=audio 13850 RTP/AVP 8 0 3 97 7 110 18 101 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:3 GSM/8000 a=rtpmap:97 iLBC/8000 a=fmtp:97 mode=30 a=rtpmap:7 LPC/8000 a=rtpmap:110 speex/8000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 RECORDING CUTS OFF AFTER 60 SECS WHEN SDP IS.. v=0 o=voip 302847118 302847118 IN IP4 77.240.60.4 s=voip c=IN IP4 77.240.60.4 t=0 0 m=audio 13622 RTP/AVP 8 0 3 97 7 110 5 10 18 112 111 101 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:3 GSM/8000 a=rtpmap:97 iLBC/8000 a=fmtp:97 mode=30 a=rtpmap:7 LPC/8000 a=rtpmap:110 speex/8000 a=rtpmap:5 DVI4/8000 a=rtpmap:10 L16/8000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:112 AAL2-G726-32/8000 a=rtpmap:111 G726-32/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:20 Can anyone tell me the significance of the o=voip, s=voip as opposed to o=root,s=session? Is this likely to be the cause of the problem and any idea how I fix it? Many thanks as always Andy Ayers
