Cannot call in or out after integration

[carrie@bluesky]

I set up 2 extensions to test the 3cx Direct Routing and I get the attached errors in 3CX.
I cannot see why this would be happening, Is it a problem that we are seeing the port 5061 on the requests?

I'm pretty lost here as to what could be going on.

Hi!

We have prepared an FAQ with the most common misconfigurations and issues that occur with the Teams Integration.

Can you check these 2 points specifically that could be causing the issue you are facing?
