I know the subject is amusingly simple it seems
We had an internet outage today, and even though our Asterisk PBX is inside the building, and the phones are configured to connect to the LAN IP of the PBX (not using hostname) they still lost all connectivity to the PBX for some reason.
I'm wondering why that is. Could it have something to do with externalip=(WAN IP)??
It doesn't seem the issue is very obvious! And what i mean by no connectivity as in they couldn't connect to the PBX to check voicemail or or call other internal phones.
