3CX PBX Failover with SIP Trunks

[rtstech]

Hi All,

Just want to ask if someone has come across a similar issue like us.

We have two PBX's (Active/Passive) setup and two SIP trunks (Active / Passive) setup. Our SIP provider is Gamma, and we use IP based trunk.

First Issue - Backup from Primary contains SIP trunk information of Primary, therefore when we restore the backup on Secondary it overrides SIP trunk info of secondary. Can't seem to find a way to exclude SIP trunk information from the backup, or automate the modification of the secondary SIP trunk after the restore, any thought?

Second Issue - One of the information apart from SIP trunks info, backup also includes is Primary Public IP for "SIP Trunk > Options > Adnaced > Put Public IP in SIP Header", from what I understand without the Public IP no outbound calls can be made (No IP is mentioned on the invite - If removed).

Will appreciate any help

Thanks
RTS

@Lee Cramman Yes, native heartbeat monitors the SIP server on primary, to monitor the SIP trunk we have created our own scripts to check the Gamma endpoint and trigger failover if the Primary Gamma endpoint is down.
