SIP Trunk Failure (Maybe)

Hey guys!

Running FreePBX13.0.188.8 with all modules updated to latest. Asterisk 13.7.2.

Does anyone know if there is a command or way to reset (reregister a trunk) without rebooting the box?

I am still having trouble with the SIP connections to our Avaya Session Managers. Periodically (no real consistency) it looks like Session Manager throws a 408 error on the SIP entity monitoring log and shuts down the connection (reports connection down). I tried turning off entity monitoring on the Session Manager side, and it was stable for almost two weeks before we saw it pop back up.

On the FreePBX side, everything looks like it is fine (Trunk status OK, port 5060 still open, and I can still ping the individual Session manager IPs). Once I reboot the FreePBX box, the connection resets and everything is fine for the next X period of time (could be weeks, days, hours), until the issue repeats.

To get it to come back up, I have to reboot the FreePBX box. After that it works perfectly. The problem is I lose pending callbacks, and other activities in the reboot.

Thanks in advance!

The PJSIP channel driver has a CLI command “pjsip send register” but chan_sip doesn’t have one I believe. It would need to be executed outside of FreePBX on the Asterisk CLI.
