With hybrid work here to stay, the challenges of cross platform communications for both internal and external meetings have led to multiple ‘interoperability’ announcements since 2020. Previous Wainhouse research revealed over 50% of companies maintain at least two communications platforms or more, making cross platform meetings an inevitability. While ‘guest-join’ functionality has enabled room-based systems to connect with other communications platforms, the capabilities lack many of the features available when meeting on the room’s native platform. With the announcement of Microsoft Teams Rooms running on Cisco devices in mid-2022, these limitations of interoperability may be coming to an end.
