Hello, I have a trouble with t.38 and an ATA "Patton 4022" (latest firmware). I'm able to send and receive fax but I see (from mediaproxy/cdrtool web interface) that the session still remain active at the end of the call... In detail, from the point of view of opensips the call is closed (the BYE is forwarded immediately to radius) but it seems that mediaproxy doesn't recognize the end and the t-38 protocol because the session is only "audio" and not "audio/image" and the it is closed only for timeout (conntrack_timeout). With an ATA grandstream ht-503 all is ok.
I have seen that the Patton SIP INVITE packet has less information than HT-503: PATTON 4022 --- From: <sip:1...@domain>;tag=afdd756f. To: sip:1...@domain;tag=ZG609-1Z1vX.
