Direct Routing for Microsoft Phone System with Cisco UBE

[Joe_Tseng1]

In this solution, is there any way to verify that Cisco UBE is successfully communicating with the Teams phone system？

I can only use Teams to make calls to see if the call goes to Cisco UBE. Thx.

Yes several ways. Such as:

• Make an inbound call from the PSTN to a direct routing enabled user / telephone number in Teams. 
• Turn on debugging (debug ccsip messages) to look at the SIP OPTIONS ping traffic between the CUBE and the MS Teams SIP Proxies.
• Issue the command show sip-ua connections tcp tls detail on the CUBE to verify TLS connectivity between the CUBE and Microsoft. Also show tcp brief is an option as that will show you have TCP connectivity between your CUBE and Microsoft.
• Issue the command show dial-peer voice summary to check the dial-peers facing Teams are showing as active

TBH, if you've followed the direct routing document, the last three points I made should show positive messages.
