Your organization will need to use Microsoft Teams as your calling solution. Additionally, your organization will need to use a phone system as part of E5 or acquire as an add-on. You will also need to choose a Calling Plan, Direct Routing, or a combination to make and receive calls.
Direct Routing allows customers to connect their telecom voice trunks directly to Office 365 so users can make and receive calls. Customers can work with their local telecommunications provider to connect their voice trunks via a certified SBC (Session Border Controller) to Office 365 and Phone System. This will be available in any country where we license Teams and Phone System. Direct Routing is part of the Teams-compatible Phone System.
A Calling Plan is an add-on telephone service that, when combined with Phone System in Office 365, can become the voice solution for your entire organization. A Calling Plan provides users with a primary phone number and lets them make and receive phone calls.
