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: Tx-Frame Retry[000] -- OSeqno: 000 ISeqno: 000 Type: IAX Subclass: POKE

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.
