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 Call Manager.

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

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

    The line number on Cisco Unified CM needs to be associated to the User ID for the Call History to be populated with the username.

    From Cisco Unified CM Administration, use the DevicePhone, select the phone and click on the Device Name (Line) and then click the required line from Association panel to get to User Associated with Line.

    • Contact Name

    • Contact Phone Number

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.
