Supplied log files are clean: asterisk startup, one extension, one call attempt, asterisk shutdown so not too much crap in them
Ata is Welltech 3701B with latest Firmware

This actually looks at an issue with the Cisco. It sends a reinvite to go back to RTP after the T38 invite, presumably before the fax has completed. Quite curious.

After looking at this again I am convinced it is a Cisco issue.
