Microsoft Teams - Using the SIP Gatway

While native Microsoft Teams phone devices provide the complete Teams user experience, we still met customers with an bunch of legacy SIP devices. In order to help these customers with their migration to Microsoft Teams, Microsoft has launched the Teams SIP Gateway. This is a cloud service that enables core Teams calling functionality on compatible SIP phone models from Cisco, Poly, Yealink and AudioCodes.

I’m going to describe the steps on how to provision SIP phones for Teams calling using this SIP Gateway with a Cisco CP-7841 IP Phone.
