[Serusers] reINVITE with port-change via mediaproxy

Hi, I've tried mediaproxy and it works for "normal" audio streams, but doesn't work for T.38 reINVITES with different RTP ports. Can anyone confirm this or does anyone have a solution? Scenario: A sends INVITE to SER with SDP audio, port=5004 SER sends INVITE to B with SDP audio, port=35004 (mediaproxy port) B sends OK to SER with SDP audio, port=5004 SER sends OK to B with SDP audio, port=35004 Now G.729 audio is proxied via mediaproxy correctly, until: A sends reINVITE to SER with SDP image, port=6004 SER sends reINVITE to B with SDP image, port=35004 B sends OK to SER with SDP image, port=6004 SER sends OK to B with SDP image, port=35004 A and B now send T.38-packets to mediaproxy, which doesn't forward them to the endpoints (neither to port 6004 nor to 5004). There is also only one session shown with session.py (I guess the G.729-session on ports 5004-5004). It seems that mediaproxy doesn't open a new pair of ports for this reinvite. It then works again with G.729-audio after the fallback: A sends reINVITE to SER with SDP audio, port=5004 SER sends reINVITE to B with SDP audio, port=35004 B sends OK to SER with SDP audio, port=5004 SER sends OK to B with SDP audio, port=35004 It's not possible to configure the UACs to use the same port for G.729 and T.38 (Mediatrix 2102) for a workaround.
