Hi everyone,

For a while, from time to time, the PBX was not able to re-register to external trunks until the PBX was rebooted.

Today I have been able to make tests and find out that when the router between Internet and the PBX is restarted, the PBX is not able to re-register. Whatever is tried, even restarting Asterisk do not work. The PBX must be rebooted to have it re-register.

The extensions works from both LAN and WAN.

Re-registration goes on every 60seconds without success until the PBX is rebooted. The same has been tested with 2 providers.

Anyone have a solution that could fix this ? This is really a PITA… I actually have Zabbix monitoring “pjsip show registration” output and send alerts when trunks are down, but rebooting PBX should not be a solution…
