Shared line appearance in Microsoft Teams

Shared line appearance lets a user choose a delegate to answer or handle calls on their behalf. This feature is helpful if a user has an administrative assistant who regularly handles the user's calls. In the context of shared line appearance, a manager is someone who authorizes a delegate to make or receive calls on their behalf. A delegate can make or receive calls on behalf of the delegator.


This feature is only in Teams Only deployment mode. For more information on Teams deployment modes, see Understand Microsoft Teams and Skype for Business coexistence and interoperability

Dialing Permissions and Routing

When a delegate makes an outbound PSTN call on behalf of a delegator, the delegator's settings control the checks for appropriate licensing, dial-out restrictions, and call routing.

License required

Managers and delegates must have a Teams Phone license. Managers must have a phone number assigned, PSTN connectivity, and a required license for PSTN connectivity: Calling Plan, Operator Connect, or Direct Routing. The shared line experience is part of delegation and is included with Teams Phone. For more information on licensing, see Microsoft Teams service description.


A delegate without a phone number assigned must be EnterpriseVoiceEnabled using the Teams PowerShell cmdlet Set-CsPhoneNumberAssignment -Identity <user> -EnterpriseVoiceEnabled $true, see Set-CsPhoneNumberAssignment.

Managers can add up to 25 delegates, and delegates can have up to 25 managers. There's no limit to the number of delegation relationships that can be created in a tenant.

If the delegator and delegate aren't in the same geographic location, the PSTN provider must allow caller ID to show up from a different geographic location for a delegated call.

Circular delegation configuration isn't permitted. If the delegated users also have delegations between them, they'll only be able to see their delegation and not the initial delegation.

Enable delegation and shared line appearance

You enable delegation by using the TeamsCallingPolicy AllowDelegation setting. You can use Teams admin center or Teams PowerShell. This setting is turned on by default.

When enabled, the end user can configure their delegation relationships directly in Teams.


When you turn off delegation for a user, you also need to clean up delegation relationships for that user in the Teams admin center to avoid incorrect call routing.

Use Teams admin center

To configure delegation and shared line appearance:

  1. In the navigation menu of the Microsoft Teams admin center, select Voice > Calling policies.

  2. Choose the policy you would like to update or select Add to create a new policy.

  3. Toggle Delegation for inbound and outbound calls on.

  4. Select Save.

Use PowerShell

To configure delegation and shared line appearance by using Teams PowerShell, use the following cmdlets:


In the following example, is added as a delegate of with permissions to make and receive call on behalf of user1, and to change settings for other delegates:

New-CsUserCallingDelegate -Identity -Delegate -MakeCalls $true -ReceiveCalls $true -ManageSettings $true

In the next example, delegate isn't allowed to make calls anymore on behalf of user1:

Set-CsUserCallingDelegate -Identity -Delegate -MakeCalls $false

In the next example, is removed as a delegate of

Remove-CsUserCallingDelegate -Identity -Delegate
