We host our own Debian Linux instance of 3CX v18 Enterprise in-house and have two broadband lines into our office, both have a static external address. We currently use "Line1" for 3CX, should it fail, we would like to change to "Line2", should both fail, we would like to use an off-site instance (I have an identical box at my home which again has a static IP address).
When switching lines, we will need the external DNS to update so ..
Question 1:
Assuming the appropriate port forwarding is done for "Line2" in the office, do I simply update this .. Settings > Network > Static Public IP to the effect the change ?
Question 2:
Likewise, should I need to deploy the unit at my home do I simply update the same setting?
I understand that office based phones won't work during full outage, so should the unit at my home be called into play, our operators will switch to mobiles using the 3CX app.
