Hello All
We are going to see , how to block the SPAM calls in Microsoft Teams Tenant Level
Even though spam call notification feature automatically evaluates incoming calls and identifies probable spam calls as “spam likely” in the calling policy, Users still have the option to answer or reject the call
Whether it’s spam, telemarketing, or general nuisance, interruptions like this to your working day aren’t welcome. Whether it’s spam, telemarketing, or general nuisance, interruptions like this to our working day aren’t welcome.
One of the more hidden features in Microsoft Teams
is the ability to block incoming calls from a number or a range of numbers at
the organisation level. This isn’t something that’s visible or available in the
Microsoft Teams Admin Center and requires the use of PowerShell.
So please use the below powershell commands to
execute
Identity : Global
InboundBlockedNumberPatterns : {}
InboundExemptNumberPatterns : {}
Enabled : True
Name :
DefaultBlockedCallingNumbers
To add
Identity :
TestBlocknumber_01
Name :
TestBlocknumber_01
Enabled :
True
Description : BlockTest
Pattern :
^\+?919003111180$

Once active, rules simply cut the calls off at the
other parties end immediately.
Depending on the carrier or network used by the
person making the incoming call they will either be simply disconnected or they
will get a message stating that their call cannot be completed.
In my test, it rings first and got disconnected
