Hello,
I've a case where MS Teams, the mobile app was working fine until suddenly it didn't. Every time we try joining a call, we get the message "we couldn't complete the call". Is there a reason for this? Does anybody have any idea how to resolve this?

Had the same issue FIXED, this was bad advice from Veejay btw...
Normally its a permission issue.
Go to settings on your phone or tablet, go to app settings, go to permissions, allow voice, camera, location etc.... Just allow all of them and it should work fine.
Hi..
Things like that happens sometimes during to a few errors at the processes of the Cloud computing..
First,try resingning your account..°^°
If still,update to latest version and then clear the catch..✓
Ha?!!contact admin or clear data by reinstalling :(
After reviewing the iphone app logs, it seemed like there was a bad server response from the cloud services related to authentication when joining meetings with voice. I considered that the MS cloud services must be clustered, so I continued to log out and back in until a different server authenticated me, and my issue went away.
To confirm my suspicion, many of the teams users in my office began to have the same issues concurrently with me. I had them all perform the repetitive logoff/logon process until their issues went away.
Presumably, MS has now resolved the server issue.
If you are facing this issue on IOS, please update your app from app store.
After updates it works without any issue.
I’m having the same issue starting this morning. App on my laptop works, iphone app does not. I restarted the phone, tried without wifi, to no success. I removed the app from the phone and reinstalled and authenticated. It worked for 2 hours after that, but then failed again.
