Third Party Video Interoperability Native Approach

Built-in registration logic

May have other built-in capabilities (RTV, CCCP, etc.)

Main advantage is a consistent architecture

Gateway Approach Gateway performs registration

Gateway may also transcode RTV (may be an additional gateway)

Main advantage is time to market

Third Party Video Interoperability Regardless of technical integration approach, third parties add…

Cross-protocol interoperability (H.323, ISDN, TIP, etc.)

High definition conferencing

“Hollywood squares” experience

Multi-codec support (H.264, etc.)

Extension of Lync to room systems

Each vendor has different approaches and capabilities within their solution set so make sure that the vendor you choose has the right integration and roadmap for your long term plan
