Hmm, it looks like I have to edit channels/chan_iax2.c to lower the 
registration timeout - I'm trying 15 seconds, and we'll see if that 
makes a difference. (You have to override the provider's requested 
timeout of 60 seconds).

Does anyone have any idea what the IP/port PAT pair timeouts are for the 
Sonicwall TZ170? I see that someone had a similar problem (PAT timeouts, 
on an unknown device) here:
