Using your existing UCM Calling infrastructure, Webex Calling integration with Microsoft Teams is a powerful way to collaborate and communicate within Microsoft Teams.

Cisco Webex Calling integration for Microsoft Teams is an application within Microsoft Teams that enables the user to make voice and video calls using Call Manager. With a single click from within the Microsoft Teams interface, you can have access to all advanced calling capabilities of Cisco Unified CM.

Currently, only Call History service is supported. Voicemail and In-call Presence integration for UCM will be added in the upcoming releases.

Known Issues

Call history records aren't populated for calls made to Hunt pilot numbers and received by the Hunt pilot Agents. Following is the behaviour currently:

  • Alice calls Hunt pilot

    Agent1 answers the call. Alice sees the history record for Hunt pilot. But, Agent1 doesn’t see any record.

  • Alice calls Hunt pilot

    Hunt pilot has two agents (Agent1, Agent2) configured and none of them answers the call. Alice sees two call records for the same hunt pilot. But, Agent1 or Agent2 don't see any record.
