How Teams Telephony works

Whether in the office, working from home or on the move, with Microsoft Teams, your employees can make calls securely, regardless of location. As you are connected to the cloud, there’s no need for a physical telephone system and your employees are able to communicate with each another and with customers via the desktop and mobile app in exceptional voice quality.


Microsoft Teams Telephony from Swisscom can be used by any Microsoft 365 business customers. Availability of the telephony functions in Teams requires a Teams phone licence.
