Session Border Controllers certified for Direct Routing
Microsoft partners with selected Session Border Controllers (SBC) vendors to certify that their SBCs work with Direct Routing.
Microsoft works with each vendor to:
Jointly work on the SIP interconnection protocols.
Perform intense tests using a third-party lab. Only devices that pass the tests are certified.
Run daily tests with all certified devices in production and pre-production environments. Validating the devices in pre-production environments guarantees that new versions of Direct Routing code in the cloud works with certified SBCs.
Establish a joint support process with the SBC vendors.
Note
Microsoft only supports Phone System with Direct Routing when used with certified devices. In case of issues, you must contact your SBC vendor's customer support first. If needed, the SBC vendor will escalate the issue to Microsoft via internal channels. Microsoft reserves the right to reject support cases where a non-certified device is connected to Phone System through Direct Routing. If Microsoft determines that a customer's Direct Routing issue is with a vendor's SBC device, the customer will need to re-engage the SBC vendor for support.
The certification is granted to specific SBC firmware versions. Any SBC firmware version documented in this article is both certified and supported. Firmware versions that are higher than what is documented are supported as long as the major.minor version is the same.
Example:
- Supported 6.10.258 - In this case, Microsoft supports firmware versions 6.10.(258 or higher).
- Recommended 6.20.100 - In this case, Microsoft recommends firmware versions 6.20.(100 or higher).
- For supportability questions about specific version, reach out to your SBC vendor.
The tables that follow list devices certified for Direct Routing. (For information about which SBC vendors support Local Media Optimization, see Configure Local Media Optimization for Direct Routing.)

Note that we're not accepting new nominations for certification until further notice.

Note the certification granted to a major version. That means that firmware with any number in the SBC firmware following the major version is supported.
To provide feedback about Teams, such as ideas for new features, see the Microsoft feedback portal.
Note
Media re-targeting is not supported. During a Direct Routing call, if the SBC sends a new media IP to Teams Direct Routing, although it's negotiated in the SIP signaling, the media is never sent to the new IP address from Teams Direct Routing.
