I am becoming more convinced that this is a nat issue, since I have installed Asterisk on the firewall itself, and it seems to run normally with no issues when restarting. The feedback from the Asterisk peer support site was that: Asterisk is sending OPTIONs, but the peer is not replying, or the request or replies are getting lost, in the network. Possibly an automatic NAT or firewall rule has timed out. There is no evidence of anything wrong with Asterisk.

Is there anyway to specify the UDP connection timeout?

Ian,
I should have looked at your dump first. I see the helpers are still loaded despite you telling them to not load. That could be because something other than shorewall loaded them.

I know on CentOS it is rmmod "module", so rmmod nf_conntrack_sip. I'm not so sure for Debian. Maybe it is:

modprobe -r nf_conntrack_sip
modprobe -r nf_nat_sip

Then see if the remote extensions magically reconnect.
