Hi,
When I try to place a T.38 FAX call to Mediation Server, I get the following error from mediation server.
SIP/2.0 488 Invalid SDP: Mismatched media name
The SIP message which caused this had the following SDP payload (relevent to T38 signaling):
m=image 16704 udptl t38
a=T38FaxVersion:0
a=T38MaxBitRate:14400
a=T38FaxRateManagement:transferredTCF
a=T38FaxUdpEC:t38UDPRedundancy
Questions:
1. Does mediation server support T.38 fax?
2. If yes, what types of SDP signaling does it expect?
RFC3362 (udptl t38) or RFC4612 (audio t38) or something else?
