Video/Audio calls not working

[Samir_Benkhellat]

Hi Team

   Since 2 weeks I have troubles with calls (video/audio) on TEAMS (desktop version):

When I call, I get this error message (I can't attach screen shots):

Sorry, we couldn't connect you

  When anyone calls me it goes straight away to the voicemail box even if my TEAMS is active and online. I don't see any incoming calls(audio/video) 

   I noticed also that :

 - I see missed calls after that on my desk version for the call I didn't see.

- Even when my desk TEAMS is active, I still get TEAMS calls on my cell

- If I disable notification on my TEAMS on my cell, I still don't get any call on TEAMS on my desk

- The web version is working on my desk but I can't use it because the share screen is too small.

This is what I've done so far:

- I made sure my Windows 10 is up to date (10.0.19044)

- I made sure TEAM is up to date as well : 1.5.00.28567

- I restarted the computer

- I deleted all TEAMS cache %appdata%\Microsoft\Teams

- Uninstall and install TEAMS from scratch

- I made sure that the option Calls ring me is selected on TEAMS on my desk

- I made sure that the option When active on desktop is blocked on my TEAM on my cell (Notification\Block notification )

- I made sure that in Office 365 administration center, coexistence mode is set to Teams Only

- I made sure that in Office 365 administration center, the voice routing is by default (same as my colleagues)

Regards

If others can't hear you in Teams calls and meetings, you might be having a problem with your microphone.
Here's how to check:
Open System Preferences.
Select Security & Privacy.
Under Privacy, choose Microphone on the left.
Make sure Microsoft Teams is selected.
Close all apps and restart your device.

Greeting,

I don't reach this step: I'm not able to make or receive any video/audio calls.So my calls fails right a way

It's not the fact that I can't hear/see them or they can't hear/see me.

Are you still encountering this issue? Also, does this happen in the Teams web client?

@roman_frillarte
As I didn't receive any helpful reply so I reinstalled windows and now it works

rergarding your request, Yes it was working on the web version but not on the desktop one.

@Samir_Benkhellat So you reinstalled the Windows operating system completely, and now it works? Glad it works now!
