Source note · Troubleshooting Teams Direct Routing
Microsoft planned a staged validation test starting June 30 2026 at 09:00 UTC, running over 2-4 days, to move Direct Routing SIP endpoints to certificates from a new CA. It said that SBCs failing outbound TLS or rejecting inbound connections during the test indicated trust issues with the new certificate.
