Integration of Microsoft teams with CUCM

[Yohan1]

Are we need any integration license to connect Microsoft Teams with CUCM?
Also, what licenses are required on the Microsoft Teams side?

[Roger Kallberg]

There is no need for any license on the CM side to integrate Microsoft Teams. What is needed on the Microsoft side is best asked on a Microsoft forum.

[Jonathan Schulenberg]

Depends on what your definition of integrate. If you intend to use the Cisco Call for Microsoft Teams client-side integration, then @Roger Kallberg is correct that there is no additional license on the Cisco side beyond the named user / knowledge worker entitlement that human is already consuming.

If you intend to migrate users from CUCM to Microsoft Phone System and have internal call routing between the two platforms you will need a SIP SBC such as CUBE for Direct Route. CUBE is licensed by concurrent call.
