My guess is that something it didn't like in SDP. [offer] v=0 o=- 3800 3800 IN IP4 10.99.1.1 s=- c=IN IP4 10.99.1.1 t=0 0 m=audio 64580 RTP/AVP 18 8 0 101 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15
[answer] v=0 o=iS3000 1 1 IN IP4 10.99.11.1 s=- c=IN IP4 10.99.11.1 t=0 0 m=audio 49398 RTP/AVP 18 96 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:96 telephone-event/8000 a=ptime:40 a=sendrecv (1) Probably the UAC didn't like that fact that the dynamic codec 101 is being mapped to 96 for telephone-event. Also, may be a=fmtp is not included in the response. The c= line ipaddress shouldnot be a problem because the receiving ports are different.
