Pexip Service: Microsoft Teams Rooms SIP/H.323 calling
The Pexip Service enables customers who have Microsoft Teams Room devices with Pro licensing to make and receive 1:1 (also referred to as point-to-point) SIP/H.323 video calls with VTCs, and to call into a third-party SIP or H.323 enabled meeting such as Cisco Webex, Zoom, GoTo, and Google Meet.
This guide provides everything you need to know about Microsoft Teams SIP/H.323 calling (also known as Connect for Microsoft Teams Rooms) — how it works, what licenses are required, and how to configure it on your Microsoft tenant.
