What is Direct Routing?
Direct Routing is a capability of Phone System in Office 365 to help customers connect their SIP trunks to Microsoft Teams. In the simplest deployment model, customers start with SIP trunks from their telecommunications provider. Next, customers will use and configure a supported Session Border Controller (SBC) from one of our certified partners. Finally, they will connect their SBC to Microsoft Teams and Phone System.
Customers will need to focus on these key areas for a successful self-managed preview:
OFFICE 365. Ensure your Office 365 tenant is ready for a Direct Routing preview by having Teams working and ready for use. Begin piloting Teams today prior to getting the Direct Routing Preview started. You will also need to have Phone System in your Tenant. Phone System comes with E5 or can be acquired separately.
SESSION BORDER CONTROLLERS (SBC). Arrange to work with one of our partners who are being certified for Direct Routing. Due to the criticality of Enterprise Voice, Microsoft has been working closely with these partners to ensure compatibility. These vendors are in process and plan to have their SBC certification complete at the time of General Availability. Please review the content for Direct Routing from AudioCodes, Ribbon, and ThinkTel to understand their offers and start a pilot with them.
