Calls coming in from numbers I've blocked

I have blocked spam telephone numbers in my Windows team client and yet they still ring. Why is that?

So my question is very simple: How can I make a "block" actually block the incoming calls?

Microsoft Teams Version 1.6.00.18681

    I have exactly the same issue. Microsoft support proving to be utterly useless (as usual).

    When the blocked number rings my Teams client on both my phone and my desktop applications, it even has an icon on it stating that the number has been blocked.

    It's clearly a bug but Microsoft are too incompetent to do anything about it.

    You can block numbers from the whole tenant (rather than an individual user) using a Powershell script and a regex - but make sure to test that your regex works.

    We're also having this issue with users unable to block callers. Three calls to Microsoft support 6 months or so apart, have said the same thing, that its a known issue and they're still looking into it.

    We don't really want to block the number from the whole tenant, as they may need to call another team.

    At the moment, we've just suggested that they save the contact as a Block Number, so they know to just reject the call if it pops up. Not ideal, but only current workaround.

    Hello Murray,

    Thanks for contacting us, I'm sorry to hear that you are still receiving calls from numbers you've blocked.

    There are a few possible reasons why this might happen:

    • The blocked numbers may be using a different caller ID or spoofing their number to bypass the block list. This is a common tactic used by spammers and scammers to trick people into answering their calls. To prevent this, you can block calls with no caller ID by going to Settings > Calls and turning on the option to Block calls with no caller ID.
    • The blocked numbers may be calling you from a different device or service that is not connected to Microsoft Teams. For example, if you block a number on Teams, but they call you from Skype or WhatsApp, the block will not work. To block calls from other services, you may need to use their respective settings or features.
    • The blocked numbers may be part of a group call or meeting that you are invited to or joined. If you block a number on Teams, but they are in the same group call or meeting as you, the block will not apply. To avoid this, you can decline or leave the group call or meeting, or mute the person you want to block.
    • The block feature may not be working properly due to a bug or an update issue. If you think this is the case, you can try to update your Teams app to the latest version, sign out and sign back in.

    I hope this helps you understand why you are still getting calls from blocked numbers and how to stop them.

    Regards, Sola
