You’ve got a loop; your inbound call is being sent back out to Telnyx. Doesn't look like there’s a DID match in your inbound routes.

Certainly it's shady; Microsoft needs to know that you are a "big company" that they would like to work with in the event that there is a support issue with your product. The way they know that is (in my opinion) 10% about the technical certification and 90% about the money and resources you are...

You work for Microsoft but you are not able to get access to a Microsoft-certified SBC? One issue that has been a snag with the FreeSWITCH SBC solution for Teams is that it is not certified and Microsoft's documentation says they reserve the right to reject any support requests related to...

I used an ACL to match calls coming in from the Microsoft gateway and then transfer those to internal context.

That looks right to me. Instead of using local siptrace I enabled HEP and pick it up with sngrep, for when I had to do tricky SIP debugging.

It depends on what version of it you currently have and how you installed it and freeswitch.

We encountered this error due to outdated version of libsrtp. Versions 1.5.x seem to be the problem.

Enabling SIP debugs will help you see what is going on. I'm not trying to be tricky but at the same time I'm not going to post everything verbatim as it took me numerous hours of research to work through the Microsoft specifications and configure the FreeSWITCH profile and gateway accordingly...

Thanks!

You don’t need Record-Route unless you are going through a proxy.

Gateway parameter "ping" with value 60 will generate one every minute toward the gateway.

No. Just curious, what are people stuck on? I haven’t seen a write up for freeswitch specifically but configuring the profile and gateway according to the Microsoft SBC specifications document worked fine for me. Disable REFER because freeswitch can’t handle the odd REFER that the MS gateway...

I have two installations that prove otherwise. I thought maybe you gained some extra features by inserting the proxy.

Does kamailio/opensips give some advantage over a direct connection between FreeSWITCH and Teams?

Just wanted to say, I brought this up in the Slack channel and was ignored.
