I have two FS servers on the same LAN, one for receiving FAXIN and one for transmitting FAXOUT FAXOUT receives an originate via ESL to send a number that routes to FAXIN via a local FS GW. FAXIN directs call to python script via dialplan FAXIN drops call 10 secs after negotiation result with this error mod_spandsp_fax.c:500 Fax processing not successful - result (13) Unexpected message received. When I enable fax_enable_t38 and fax_enable_t38_request, this same call succeeds. This seems like bad configuration on FAXIN, but I receive some faxes from remote destinations without t38. -- James Lyons QuikVoIP, LLC. p: +1 (786) 369-5308 w: www.quikvoip.net
