Telephony over Teams is part of the Microsoft Teams application, supported by the Chorus and Nexus teams
Notice: Telephony replacement project
In response to BT switching off analogue lines in late 2025, the Telephony Replacement Project is currently coordinating the replacement of centrally managed analogue and critical phone lines. In future (likely later in 2025) the project will also be reviewing the Chorus VOIP (digital line) service. For more information see the Telephony replacement project webpage.
These pages will give you information about how to use Telephony over Teams.
