Frequently asked questions on cloud calling with Microsoft Teams

  • The licenses don’t necessarily have to be purchased from Sunrise. If you obtain your Microsoft Teams licenses from another provider, we can effortlessly install them into our cloud-based phone solution.
  • Connection takes place using an SIP Trunk (Sunrise Business voice direct cloud connect) which allows for an IP connection to the public phone network. All the necessary hardware components of the SIP Trunk are located in the high-availability Sunrise data centers. For more details, please refer to Managed SIP Trunking or the flyer on Business voice direct cloud connect (PDF).
  • Sunrise first activates the cloud-based calling solution SBV Cloud Connect (Managed SIP Trunk) and activates (or connects existing) Microsoft Teams licenses.

    Afterwards, the calling solution SBV cloud connect with Microsoft Teams is activated by our Professional Services Team.

    There is no need for on-site installation.
