Microsoft Teams Phone turns Microsoft Teams into a fully-fledged telephony solution. Make calls, chat and hold online meetings directly in your familiar Teams platform – without additional applications or a high-maintenance telephone system. Your telephone numbers are integrated into the Microsoft 365 environment, either via Operator Connect or via Direct Routing . The factsheet  and the General Terms and Conditions for Business Customers of Sunrise LLC apply.  

The solution is particularly suitable for: 

• SMEs with an existing Microsoft 365 environment 

• Companies that want to replace their traditional telephone system 

• Organisations with hybrid or mobile working models 

• Companies that favour flexible and controllable solutions 

Your employees work in a familiar environment, while IT benefits from a lean, centrally managed solution without maintenance-intensive hardware. This reduces complexity, training and operating costs. 

You can manage everything yourself via the Sunrise Marketplace and the Sunrise Business customer portal, quickly and without having to contact the provider, for example, via a hotline: 

• Add Microsoft Teams Phone Standard user licences  

• Change Phone tariff plans (Pay2Go, Swiss Flatrate, Global Flatrate) on a monthly basis within the 12-month minimum contract term 

• View costs and usage transparently 

Yes. You can add Microsoft Phone licences for new employees flexibly and easily yourself – quickly, in a standardised way and without the complex conversions required for a physical telephone system. 

A stable Internet connection and either a Microsoft Teams Essential or Microsoft 365 licence are required for SME Ready Microsoft Teams Phone. These are not included in the SME Ready Microsoft Teams Phone product.  

You can purchase and manage the Microsoft Teams Essential or Microsoft 365 licence directly via the Sunrise Business Marketplace . Don't have access to the Sunrise Business Marketplace yet?

The Sunrise Business Marketplace is an online shop where you can order and manage your Microsoft 365 licences and Teams Phone licences online. See also the previous question. 

When both telephony and Internet come from one single source, you benefit from an end-to-end solution without interface problems and with network prioritisation of voice packets (quality of service) over other data traffic. In the event of faults or questions, one contact person takes care of all your concerns – so problems are recognised more quickly and solved efficiently.
