[asterisk-users] IAX2 help needed...

[Ade Vickers]

I run a phone in a remote office using the IAX2 protocol. It mostly works
fine; except that every 5 mins it loses connection with Asterisk, before
reconnecting 30 seconds later; rinse & repeat.
 
Using the IAX2 debugging, I'm seeing this a lot:

Note in particular:

Whenever this happens, the phone loses connection until a REGACK is
received.
 
 
This started happening when I upgraded Asterisk to v 1.4.22 (from an earlier
v1.4.x), on a new machine.
 
Any ideas what I need to do to fix the issue?
 
Phone is a Quartel 710E, in case that's of any use, and it worked fine with
my previous Asterisk setup.
 
Cheers,
Ade.
