I'm trying to receive a t.38 fax from a Metaswitch 7.3. I have full
control over the metaswitch, but it is in production.
I have the Metaswitch hooked to Asterisk 1.8.7.0 (middleman named s3).
Then I have the target Asterisk 1.8.7.0 with res_fax_digum 1.8.4_1.3.0
(named pbx1) registered to s3.
attempts to receive fax over t.38 always error in res_fax with "fax
session timed-out"
i have debug output at:
http://jeremy.kister.net/tmp/t38/pbx1.txt
http://jeremy.kister.net/tmp/t38/s3.txt
is the UDPTL debug on pbx1.txt (near line 474) interesting in that
LOG_TAG(s) is evaluated to 'SIP/' ?
I don't think my (sip|udptl|extensions).conf are interesting, but i'd be
happy to post them. the only interesting tidbit is that when i changed
't38pt_udptl=yes' to 'yes,none' or 'yes,redundancy' the fax would fail
with 't38 negotiation failed".
fyi, g711/rtp audio detected faxes are working fine.
anyone have suggestions on what i can try next?
