Hi!

I just run over this info (here https://learn.microsoft.com/en-us/microsoftteams/direct-routing-whats-new) from dec 12, 2025;
———————————-
Changes and call to action

The outlined changes are applicable to Direct Routing and Operator Connect and are planned to be implemented by end of February. Microsoft Teams SIP interface certificates will come from one of the CAs listed under the 'Root Certificate Authorities' section in Azure Certificate Authority details page. 

The list of supported CAs: 

Certificate Authority: DigiCert Global Root CA
Thumbprint (SHA1): A8985D3A65E5E5C4B2D7D66D40C6DD2FB19C5436

Certificate Authority: DigiCert Global Root G2

Howdy, Stranger!
