Is there any way to trace a SIP Dialog in Microsoft Teams?

Question

Hi everyone!

Is there any way to trace a SIP Dialog in Microsoft Teams?
I mean, we have the trace dialog on our SBC, but a "SIP/2.0 500 Internal Server Error" is coming from MS Teams. I would like to know if there is any tool to check the SIP Flow coming inside Microsoft Teams and make sure what's the reason for this ERROR.

Regards!

@Luthi Castelanno ,

You can use Call Analytics, which provides standard SIP codes to help you with troubleshooting.

However, Call Analytics can only help when calls reach the internal components of Direct Routing and fail. In case of issues with SBC pairing or issues where SIP "Invite" was rejected (for example, the name of the trunk FQDN is misconfigured), Call Analytics will not help. In this case, refer to the SBC logs. Direct Routing sends a detailed description of issues to the SBCs; these issues can be read from the SBC logs.

About how to use Call Analytics to troubleshoot poor call quality, please focus on Troubleshoot user call quality problems part in this link.

Moreover, Direct Routing Diagnostic Tool is another choice. For more information, please refer to Direct Routing Diagnostic Tool section in this article.
