Is anyone having SIP Trunk Registration Problem?

PBX Down, help.

My trunk to Flowroute will not register since yesterday. I think I did a module update yesterday. Cannot locate the reason it will not register as I can ping the address ok and did not change any trunk parameters.

Any Ideas?

I suspect updating left something in a strange state. Much Rebooting and Applying Configs did not repair. Some how my trying to restore from backup and having to restore a disk image I, thankfully made before trying to restore, fixed the problem. Backup / Restore module needs debugging as it does not appear to work successfully. Backup is not much good if restore doesn’t work and breaks your system.
