User Caller ID keeps reverting

[stpaulschurch]

We use Twilio for our SIP Trunk. They require the n164 phone format for our caller IDs or it rejects our call outs. So, for each user, I change the caller id to the +1320 plus the number format and save. This works...For a short time, and then it reverts back to the 320 plus the number format, without the +1. This breaks our outbound call capabilities. I also noticed that it changes the outbound caller id to our primary number for every user. We want the outbound caller ID to be the user's n164 formatted phone number.

What am I doing wrong here?

Do you have the M365 integration enabled? If so, check if you're syncing the Office Phone as Caller ID in the integration settings.

I do integrate with M365, but I don't see where I actually change that. Is it in Azure, because in the Integration on 3cx, there's no options other than to reconfigure which just resyncs the integration.

In Users > M365 (blue button)

Ah, well then the better way still would be to fix the phone numbers at M365->Users to follow the n164 format. Thanks!
