How to block incoming calls in Microsoft Teams
Follow these methods to block incoming calls in Microsoft Teams. Check each of them and figure out what works best for you. Anyone can use the first method, while the rest IT admin can set it up for the organization. It is beneficial to avoid spam calls.
1] Microsoft Teams App
If it’s one or two numbers you want to block, then you can do it using the Teams app. Microsoft Teams Client will now display a tag for the caller as ‘Blocked’, and this user will be blocked from making further calls to any other organization members.

2] Number Patterns
You can look into blocking/whitelisting inbound calls with certain number patterns. Direct Routing, Operator Connect, and Microsoft Calling Plan support blocking inbound PSTN calls. An IT Admin can use this feature to define a list of number patterns at the global tenant level that can be checked against a list of spam numbers and reject the call automatically. However, it will work for calls originating from PSTN. Here is the PowerShell command that one can use for Number Patterns.
New-CsInboundBlockedNumberPattern adds a blocked number pattern to the tenant list.

3] Block a number
If you want to block a number that belongs to a range, which is especially useful to avoid telemarketers, then one can create a number pattern, so numbers in the range with + prefixed and numbers in the range without + prefixed are matched, e.g., 1 (312) 555-0000 to 1 (312) 555-9999. Blocking multiple numbers with a RegEx pattern or a single number are the three options available with the above. It is possible to block a single number, block a sequential number range, or block multiple numbers simultaneously Read more about it here
3] Add a number exception
If the user wants to allow 1 (312) 555-8882 and 1 (312) 555-8883 to make calls but block anything else that matches the pattern, then the IT admin can use the CsInboundExemptNumberPattern To enable this, a new number exception pattern is created as follows: You can use the Remove-CsInboundExemptNumberPattern to remove such patterns.
