A large company wants to procure video conference devices that allow multipoint conferences from C-Series and immersive endpoints that are registered to a Cisco VCS and Cisco Unified Communications…

The Cisco TelePresence Multipoint Switch is designed to trunk to CUCM, not register as a conferencing resource to VCS, so it does not serve VCS-registered endpoints.

The C-Series multisite option key supports only small ad hoc multipoint calls initiated from that single endpoint and cannot bridge immersive TelePresence endpoints or scale to an enterprise deployment.

The Cisco TelePresence Server registers to Cisco VCS as a conferencing resource and provides scalable multipoint bridging for both C-Series and immersive endpoints in a VCS-controlled environment, supporting H.323 and SIP. It is purpose-built for enterprise-grade multipoint conferences originating from VCS-registered endpoints.

A C-Series endpoint with a multisite option key registered to CUCM is limited to small peer-to-peer multipoint and lacks the capacity and interoperability needed for immersive endpoint bridging.

The Cisco TelePresence Multipoint Switch can be trunked to Cisco Unified Communications Manager, enabling MCU-style multipoint bridging for all endpoints registered to CUCM. This satisfies the requirement for the CUCM side of a hybrid VCS-CUCM deployment.
