One of the biggest challenges UC administrators face is the lack of interoperability: no
single model exists for any-device-to-any-device via a common app. Each vendor offers a
different solution or proprietary platform (which can be server-based, on-premise, or cloud
International standards or common interfaces are not yet mandated. WebRTC (Web Real-
Time Communication), which supports browser-to-browser UC applications, may gain
some traction in the future. Session Initiation Protocol (SIP), a communications protocol for
signaling and controlling multimedia communication sessions, is being more widely used.
This lack of interoperability means that UC consumers will likely end up working with
multiple vendors for the various UC system components. It is important to consider the
following factors when selecting compatible/appropriate equipment:
Ultimately, the winning solutions will be those that take into account the end customers’
ease of use, in terms of implementation, maintenance and daily use.
