Teams Real Simple with Pictures: Block Call Me within Teams Meetings

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
