Which feature enables the hosting of a multipoint conference locally on a Cisco TelePresence endpoint without the use of an external bridge?

Multisite is a software license option available on Cisco TelePresence endpoints such as the SX and MX series that allows the endpoint itself to mix and switch multiple participant streams internally, acting as its own conference host and completely eliminating the dependency on an external MCU or conferencing bridge.

MCU is an external hardware or virtual appliance used to host multi-party conferences and is explicitly the type of external bridge the question states should not be required.

'Multipoint' is a generic industry term describing multi-party conferencing as a concept, not the specific Cisco TelePresence feature name that enables local hosting on an endpoint.

VCS (Video Communication Server) is a call-control and registration device used for routing and gatekeeping, not a feature that provides local multipoint conferencing on an endpoint.

Multiway is a Cisco feature that lets an endpoint escalate an active call to a multipoint conference via VCS, but it still relies on an external conference resource rather than processing the conference locally on the endpoint.
