Microsoft Teams: Private Line feature on Teams phone devices

A new Private Line feature is specially made for users that might have a delegate line managed by assistants, admins, and so on. It lets these users get a second, private phone number for their Teams device apart from their main number for incoming calls. 

Private line calls will also have distinct ringtones and tagging in call history, ensuring clear differentiation from regular calls.

When is this rolling out

General Availability (Worldwide, GCC): We will begin rolling out in mid-July 2024 and expect to complete by late July 2024.

General Availability (GCCHigh): We will begin rolling out in late July 2024 and expect to complete by late August 2024.

How this will affect your organization:

This Private Line feature aims to give an extra level of privacy for important calls, making sure that crucial conversations stay private by getting incoming calls directly without going through delegates, admins, or assistants.

Private Line calls will also have distinct ringtones and tagging in call history, ensuring clear differentiation from regular calls.

What you need to do to prepare:

For this feature to work, you will have to set up a PSTN or VoIP contact as a private line number. Currently, private lines can only be configured with PowerShell. You must have Teams PowerShell Module version 5.4.0 or higher to use the updated CsPhoneNumberAssignment cmdlets. Use the following illustrative command to set-up a private line number using PowerShell:

• Set-CsUser -Identity "sip:[email protected]" -PrivateLine “Tel:+14255551212”
