Direct Routing partners FAQ

What are the benefits of Direct Routing?

Direct Routing is Microsoft’s original Bring Your Own Carrier (BYOC) solution for Teams—which means you can get all of the benefits from going direct-to-carrier, plus the feature-rich platform of Teams. Major benefits of Direct Routing include:

1. Communications flexibility

Direct Routing gives enterprises flexibility over Direct Inward Dialing (DID) numbers, IVR, call routing, call recording, and locations.

2. Migration control

With granular control over your numbers and on-premise equipment, Direct Routing offers a controlled, disruption-free migration path. You can move your comms stack to the cloud and host your SBC with your Direct Routing provider, or maintain your on-premise equipment for extra control.

3. Global reach

If you need PSTN connectivity in more than the ~16 countries Calling Plans are currently available in, your Direct Routing partner can offer coverage everywhere you have customers and employees.

4. Fast access to support

Compared to purchasing wholesale PSTN connectivity via Teams Calling Plans, Direct Routing gives you access to your provider’s support, network operations, and number management teams.

How can I get started with Direct Routing?

To connect Direct Routing to the PSTN for voice and emergency, enterprises need: 

  1. A Microsoft Teams Phone System license in Microsoft 365. This is typically included in the E5 package, and as an add-on for E3.
  2. A Direct Routing provider with SIP trunks and certified E911 for Microsoft Teams. Bandwidth is one of three certified E911 providers for Microsoft. 
  3. A Microsoft-certified Session Border Controller (SBC) to terminate SIP Trunks. 
  4. Trained IT personnel that can set up & manage your Microsoft Teams connectivity. 

Learn more about getting started with Direct Routing. 

How do SBCs work in Direct Routing?

Your Microsoft SBC connects your Microsoft Teams users to your Direct Routing provider. Without an SBC, there would be no way to send media and voice between devices via the PSTN. In addition to terminating SIP trunks, your SBC acts as your voice firewall. Whether you choose to host your SBC or not, Microsoft Teams will send calls to the SBC, and then to the PSTN or emergency services provider with IP-based SIP trunks.
