You also use Baltimore Cybertrust for Teams, which means we have imported this for Direct Routing on our session border controllers. Will this also change? Which Trusted Root CA will you be using for this going forward? Thank you.

    Hi @Melmix ,

    As the link said above, you can try to follow these ways to detect if direct routing in Microsoft Teams is impacted. You can search your source code for the thumbprint, Common Name, and other cert properties of any of the Microsoft IT TLS CAs found here. If there is a match, then your application will be impacted.

    The following link shows the supported trusted root CA for your reference:
