[Freeswitch-users] Fax failing due to Timer T2 expired and prematurely dropped.

[Peter Steinbach]

I would recommend a tcpdump trace and see what's happening. If
transmission is via T.38, it's not too difficult to determine, what's
happening there with Wireshark. In case if T.30 it's much more difficult
of course.
