Teams Calls on personal account failing - 'We couldn't complete the call'

Question

I have Teams on my iPhone and suddenly this week I am unable to have voice or video calls with my personal contacts. I keep getting an error message saying 'We couldn't complete the call'. I've also had someone call my personal account, and they can't get through as it says I'm 'Not available'. I have my work account on my phone and that can make and receive those calls just fine. I've tried calling from a browser too but still have the same issue. Microsoft support didn't seem to be much help, but asking Chat GPT they think it could be some kind of a presence/calling provisioning issue. Any ideas on what could be causing this?

Answer 1

What Presence status is shown on your Teams account?
