Microsoft Teams Rooms Cloud Video Interop vs. Direct Guest Join vs. Cross-Platform Meetings via SIP

Marius Nilsen, VP, Office of the CTO at Pexip, and Tom Arbuthnot compare the three interop routes for Microsoft Teams Rooms: Cloud Video Interop with its SIP Guest Join extension, the built-in Direct Guest Join in Teams Rooms Basic and Pro, and Cross-Platform Meetings via SIP, which adds 1080p, dual screen and HDMI content sharing and is coming to Teams Rooms on Android.

Joining Zoom, Webex, Google Meet or SIP meetings from Microsoft Teams Rooms (MTR)? Marius Nilsen, VP, Office of the CTO at Pexip, breaks down the three types of meeting Interop available and explains what each option means for your organisation.

• Cloud Video Interop (CVI): how it enables SIP devices to join Microsoft Teams meetings, plus the SIP Guest Join extension for joining external meetings

• Direct Guest Join: the built-in option for joining Webex, Zoom and Google Meet from Microsoft Teams Rooms, included in Teams Rooms Basic and Pro

• Cross-Platform Meetings via SIP: 1080p, dual screen support and HDMI content sharing, now coming to Microsoft Teams Rooms on Android

• How deployment works as a Cloud service with simple PowerShell setup, plus self-hosted options for more sensitive organisations

• Why customers report reduced support costs and fewer meeting join issues as one of the biggest real-world benefits

• SIP Guest Join extends CVI so your SIP rooms can join any external Teams meeting, without trusted lobby bypass.
• Direct Guest Join is included in Teams Rooms Basic and Pro and covers Webex, Zoom and Google Meet at 720p.
• Cross-Platform Meetings via SIP supports 1080p, dual screen layouts and HDMI content sharing from the Teams Room.
• Already shipping on Teams Rooms on Windows, Cross-Platform Meetings via SIP is imminent for Teams Rooms on Android.
• Pexip uses native interop into Google Meet, and the Zoom and Webex SIP interfaces, to deliver the richer feature set.
• Setup is an admin consent link plus a couple of PowerShell commands; the consent is the same one used for CVI.
• Customers report reduced end user support costs and fewer meeting join failures as the biggest practical benefit.
