Hi all, I've been facing problems receiving a re-INVITE to T.38. My app using sofia-sip sent an INVITE with the following sdp:
------------------------------------------ m=audio 4008 RTP/AVP 18 4 8 0 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=yes a=rtpmap:4 G723/8000 a=fmtp:4 annexa=yes a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 m=image 4008 UDPTL t38 a=T38FaxVersion:0 a=T38FaxMaxBuffer:1100 a=T38FaxMaxDatagram:612 a=T38MaxBitRate:14400 a=T38FaxRateManagement:transferredTCF a=T38FaxUdpEC:t38UDPRedundancy ------------------------------------------ and received a 200 in reply with the following sdp: ------------------------------------------ m=audio 6000 RTP/AVP 8 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-11,16 ------------------------------------------ Later on, received a re-INVITE with sdp: ------------------------------------------ m=image 6110 udptl t38 a=T38FaxVersion:0 a=T38FaxMaxBuffer:1100 a=T38FaxMaxDatagram:612 a=T38MaxBitRate:14400 a=T38FaxRateManagement:transferredTCF a=T38FaxUdpEC:t38UDPRedundancy ------------------------------------------ to which we tried to reply with: ------------------------------------------ m=image 4008 UDPTL t38 a=T38FaxVersion:0 a=T38FaxMaxBuffer:1100 a=T38FaxMaxDatagram:612 a=T38MaxBitRate:14400 a=T38FaxRateManagement:transferredTCF a=T38FaxUdpEC:t38UDPRedundancy ------------------------------------------ but actually got the following: ------------------------------------------ m=image 4008 UDPTL t38 a=T38FaxVersion:0 a=T38FaxMaxBuffer:1100 a=T38FaxMaxDatagram:612 a=T38MaxBitRate:14400 a=T38FaxRateManagement:transferredTCF a=T38FaxUdpEC:t38UDPRedundancy m=image 0 UDPTL 19 ------------------------------------------ I just can't figure out how to get rid of m=image 0 UDPTL 19 line which is being sent by sofia.
