Hi, I am running a build of asterisk@home with asterisk 1.2beta1 and am trying to diagnose RxFax with a Voip incoming trunk. I am running the latest spandsp and rxfax with libtiff 3.7. Switching on debug IU can see the call come in, but after a small time the fax connection drops and the sending fax (paper doc ) has not moved in the machine. I guess it must be dropping in the negotiation prelim stuff. I do have some rtp stuff about time differences and some stuff about converting from a slin codec to ulaw and dropped frames, I just dont know what is significant if anything. Can someone help me to diagnose why the line is just dropping, I have included the debug below. Cheers Paul.
