The error happens so quickly that I would suspect that it has to do with fax detection within Asterisk re-routing the call to a different place. Watch the CLI when a fax call comes in and see what happens there.

It happens so quickly that I would suspect that it has to do with fax detection within Asterisk re-routing the call to a different place. Watch the CLI when a fax call comes in and see what happens there.

However, let me say now that your setup that you describe strings the IAX2 channels out over your LAN which is no guarantee that there won't be jitter to cause you other problems. Normally iaxmodem (and probably therefore HylaFAX) should run on the same system as Asterisk.

Thanks,

Lee.
