Updated June 2, 2025: We have updated the timeline below. Thank you for your patience.

Coming soon for Microsoft Teams Phone devices: We are excited to announce the upcoming availability of shared line, collaborative delegation, call queues and call transfers on line keys on Teams certified phone devices.

Line keys on phone devices address the pain point of navigating through multiple menus to manager calls, offering enhanced call management where users can manage multiple calls effectively, increased productivity and improved user experience.

For shared line and collaborative delegation, this feature will enable you to assign shared lines/collaborative delegation lines to a line key and view the boss/delegates and members of the group (in case of collaborative delegation) along with their presence on Teams Phone devices. This feature allows delegates to pick up calls on behalf of the boss or members of the group (in case of collaborative delegation) by pressing the line key and join active calls. Also, users will be able to assign the transfer action to the line key, enabling them to transfer active calls to specific contacts by pressing that line key. Lastly, after assigning call queues to the line key users can view the status of call queue whether busy or available and receive calls by pressing line key.
