Has anyone else seen an issue with t.38 faxing on Level 3 with res_fax
and res_fax_spandsp.so
What we are seeing in the packet captuers is that the call is trying to
do t.38 but does not appear to be completing the handshaking. No data is
being transmitted. I have included a link to my pcap of this. Can anyone
give me some more insight?
cap-t38.pcap

res_fax_spandsp (and res_fax_digium) are not involved with T.38
negotiation; that is handled by res_fax and chan_sip. As I've posted in
the other thread you started, please post a complete Asterisk log
capture so that we can see what Asterisk tried to do and what the
results were. That is more useful than a packet capture, at least for
the initial debugging steps.
