List of Session Border Controllers certified for Azure Communication Services direct routing

  • Article

This document contains a list of Session Border Controllers certified for Azure Communication Services direct routing. It also includes known limitations.

Microsoft is working with the selected Session Border Controllers (SBC) vendors certified for Teams Direct Routing to work with Azure direct routing. You can watch the progress on this page. While the SBC, certified for Teams Direct Routing, can work with Azure direct routing, we encourage not to put any workload on the SBC until it appears on this page. We also don't support the uncertified SBC. While Azure direct routing is built on the same backend as Teams Direct Routing, there are some differences. The certification covers comprehensive validation of the SBC for the Azure 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 preproduction environments. Validating the devices in preproduction environments guarantees that new versions of Azure Communication Services code in the cloud work with certified SBCs.
  • Establish a joint support process with the SBC vendors.

Media bypass isn't yet supported in Azure Communication Services. The table that follows list devices certified for Azure Communication Services direct routing.
