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.
