Hi Bastien,
If you see incoming and outgoing udptl traffic on both SIP-FAX
devices, capture it and load the file on wireshark. Check the T.38
signaling and see where it is failing and why.
As an example/reference, use a capture from a working case.

Ovidiu Sas

Hi Bogdan,
I think it has nothing to do with a deadlock. I see the incoming and
outgoing UDPTL traffic on both SIP-FAX devices.
Do you got a suggestion for me, what I could do to locate and resolve the
problem.
Cheers
Bastian
