Phone System in Microsoft 365 provides a default caller ID that is the user's assigned telephone number. You can either change or block the caller ID (also called a Calling Line ID) for a user. You can learn more about how to use caller ID in your organization by going How can caller ID be used in your organization.

By default, the following caller ID settings are turned off. This means that the Teams user's phone number can be seen when that user makes a call to a PSTN phone. You can change these settings as follows:

  • Outgoing caller ID You can replace a user's Caller ID, which by default is their telephone number, with another phone number. For example, you could change the user's Caller ID from their phone number to a main phone number for your business or to a main phone number for the legal department. Additionally, you can set the Calling ID number to any online service number (toll or toll-free) or to an on-premises phone number through Direct Routing that is assigned to a resource account used by an Auto Attendant or a Call Queue.

    Note

    If you want to use the Service parameter, you must specify a valid service number. You need to use the PowerShell cmdlets New-CsCallingLineIdentity or Set-CsCallingLineIdentity in the Teams PowerShell module 2.3.1 or later for the Resource account number if it is not visible in the dropdown.

  • Block outbound caller ID. You can block the outgoing Caller ID from being sent on a user's outgoing PSTN calls. Doing this will block their phone number from being displayed on the phone of a person being called.

  • Block incoming caller ID. You can block a user from receiving Caller ID on any incoming PSTN calls.

  • Set Calling Party Name (CNAM). For your Microsoft Teams users you can send a CNAM on outbound PSTN calls.

Important

Emergency calls will always send the user's telephone number (caller ID).

To learn more about these settings and how you can use them, see How can caller ID be used in your organization.

Set your caller ID policy settings

Note

To set the caller ID to a resource account phone number and to set the calling party name, use the PowerShell cmdlets New-CsCallingLineIdentity or Set-CsCallingLineIdentity in the Teams PowerShell module 2.3.1 or later. (These options are not currently available in the Microsoft Teams admin center.)

Open a Windows PowerShell command prompt and run the following commands:

# When using Teams PowerShell Module

Import-Module MicrosoftTeams
$credential = Get-Credential
Connect-MicrosoftTeams -Credential $credential

View, create, and apply policy settings

  1. To view all of the caller ID policy settings in your organization, run:

    Get-CsCallingLineIdentity |fl

    For more information, see Get-CsCallingLineIdentity.

  2. To create a new caller ID policy for your organization, use the New-CsCallingIdentity cmdlet:

    New-CsCallingLineIdentity  -Identity Anonymous -Description "Anonymous policy" -CallingIDSubstitute Anonymous -EnableUserOverride $false

    In all cases, the "Service Number" field should not include an initial "+".

    For more information, see New-CsCallingLineIdentity.

  3. Apply the new policy you created by using the Grant-CsCallingIdentity cmdlet. For example, the following example applies the new policy to user Amos Marble.

    Grant-CsCallingLineIdentity -Identity "amos.marble@contoso.com" -PolicyName Anonymous

    For more information, see Grant-CsCallingLineIdentity cmdlet.

  4. If you want to block the incoming caller ID, run:

    Set-CsCallingLineIdentity  -Identity "Block Incoming" -BlockIncomingPstnCallerID $true

    For more information, see Set-CsCallingLineIdentity.

  5. To apply the policy setting you created to a user in your organization, run:

    Grant-CsCallingLineIdentity -Identity "amos.marble@contoso.com" -PolicyName "Block Incoming"

    For more information, see Grant-CsCallingLineIdentity.

  6. To create a new Caller ID policy that sets the Caller ID to the phone number of the specified resource account and sets the Calling party name to Contoso:

    $ObjId = (Get-CsOnlineApplicationInstance -Identity dkcq@contoso.com).ObjectId
New-CsCallingLineIdentity  -Identity DKCQ -CallingIDSubstitute Resource -EnableUserOverride $false -ResourceAccount $ObjId -CompanyName "Contoso"

If you have already created a policy, you can use the Set-CsCallingLineIdentity cmdlet to make changes to the existing policy, and then use the Grant-CsCallingLineIdentity cmdlet to apply the settings to your users.

Remove a policy setting

To remove a policy from your organization, run:

Remove-CsCallingLineIdentity -Identity "My Caller ID Policy"

To remove a policy from a user, run:

Grant-CsCallingLineIdentity -Identity "amos.marble@contoso.com" -PolicyName $null
