Hello, we have connected our SIP trunk provider with teams and according to the provider everything should have been set correctly. Unfortunately, there is still no connectivity (please see appendix). What could be the reason for this? Do we need to adjust anything else?

In this case, you might experience the following Session Border Controller (SBC) connectivity issues:
- Session Initiation Protocol (SIP) options are not received.
- Transport Layer Security (TLS) connections problems occur.
- The SBC doesn't respond.
- The SBC is marked as inactive in the Microsoft Teams admin center.
This article lists some common issues that are related to SIP options and TLS certificates, and provides resolutions that you can try.

The TLS connection not being active can be caused by multiple reasons.
Let me know if problem still exist so we can connect and see how to solve this.1 that is easily being forgotten is to import the Baltimore Cybertrust root certificate that is being used by Microsoft.
