Teams Integration problem

Hello I'm trying to integrate my SBC(OpenSIPS based) with Teams but I having an issue.

 

SIP OPTIONS transaction is working either direction between Teams and my SBC(this should also mean TLS is working?). However, when I checked the Teams Admin center it shows like that;

 

 

 

 

Even with those error if I make call from Teams client I see that SIP INVITE reaches to my SBC and my SBC responding with 200OK however I'm not receiving ACK for that call.

I'm out of ideas to troubleshoot this problem and help is very much appreciated.

Best Regards,

Ali

    Hello,

    Is the SBC on the certified list for Microsoft Teams Direct Routing?
