Ok, so this one came about after someone on Tech Community asked me if there was a way to remove the call me functionality within Microsoft Teams Meetings. Most people I talk to about it typically don’t know about it or use it, and even less on the reasons as to why to turn it off in the first instance. So lets do this. As defined by, the call me feature gives users a way to join the audio portion of a meeting by a landline or mobile. Why? Think of a scenario such as needing to get up and walk around whilst the meeting is in progress or simply because the user considers audio in that location to be better over the PSTN. They may just like the tangible feel of a device. All legitimate reasons. However, in making the Meeting call the user on a landline or mobile begins using the audio conferencing minutes pool – 60 minutes per user per month and then start using communication credits if they have burned through the pool allowance, so if the admin doesn’t know this then it could end up both rinsing their pools and credits causing them a significantly higher bill than they were anticipating – particularly if several users started to do it regularly. Therefore, the admin at least needs to know how to block and mitigate that behaviour by making users call into the meeting or stick to using VOIP audio where they could work with them to resolve any quality issues, or potentially invest in an IP phone

This blog will cover

  • Blocking the call me feature in the TAC
  • Blocking the call me feature in PowerShell


  • Teams Admin Centre Permissions (I.e. Teams Admin, Global Admin)
  • Audio Conferencing Licence (for configured users)


1.) Login to and select Admin

2.) On the left navigation, select Show All and then Teams

3.) In the Teams Admin Centre select Users

4.) Select the user to amand

5.) Under Account select Edit

6.) Select Don’t Allow and then Apply

Our job here is done.

The user will not be able to call out to mobile devices or landlines as an error will state the call could not be completed and the user is unavailable. The user will need to dial into the call on the device


This can be easily set on a user or all users – however to note from a PowerShell perspective outbound call restrictions are controlled by a single policy called OnlineDialOutPolicy which cannot be modified. More can be read here. If you wanted to block a specific user who you also wanted to permit outbound domestic PSTN calling run the following

Grant-CsDialoutPolicy -Identity “<username>” -PolicyName “DialoutCPCDisabledPSTNDomestic”

And if you wanted to block a specific user who you also wanted to permit outbound domestic and international PSTN calling

Grant-CsDialoutPolicy -Identity “<username>” -PolicyName “DialoutCPCDisabledPSTNInternational”

If you wanted to modify all users you would use one of the following

Get-CsOnlineUser | Grant-CsDialoutPolicy -PolicyName “DialoutCPCDisabledPSTNDomestic

Get-CsOnlineUser | Grant-CsDialoutPolicy -PolicyName “DialoutCPCDisabledPSTNInternational

A good way to check that the right policy is assigned to a user is to run the following command before and after using the grant command above to check that the change has occurred

Get-CsUserPolicyAssignment -Identity <username>
