Hi, sorry for the late answer, this mail got lost in my mailbox... and i think i found the issue:
These are the lines in my SBC-profile, which causes this issue: sdp_filter=whitelist sdpfilter_list=g722,pcma,pcmu,telephone-event The problem is the following: The SDP-Parser will not set any payloads for the T.38 Re-INVITE: Aug 27 11:45:21 sbc-1 sems[11207]: [#7f3dab4f4700] [parse_sdp_connection, AmSdp.cpp:705] DEBUG: SDP: got session level connection: IP4 87.234.1.224 Aug 27 11:45:21 sbc-1 sems[11207]: [#7f3dab4f4700] [parse_sdp_media, AmSdp.cpp:840] DEBUG: set media fmt to 't38' Aug 27 11:45:21 sbc-1 sems[11207]: [#7f3dab4f4700] [parse_sdp_media, AmSdp.cpp:848] DEBUG: SDP: got media: port 13362, payloads: As a result, the SBC-SDP-Filter, will set this stream to "inactive" (since no suiting codecs were found) and the SBC will reply with a "488 Not acceptable here". I've modified the filterSDP() function to only use the SDP-Filter for media-streams in the RTP/RTPS-audio-video-profiles, not others. I'll commit a patch and backport it to 1.5 / 1.4.
