Which optional feature is available for some video endpoints to enable multiparty calls to be hosted directly on the local endpoint?

WebEx enabled Cisco TelePresence is a feature that links TelePresence endpoints to WebEx meeting rooms, not an on-device multiparty hosting capability.

Multiway is a feature that escalates an in-progress call to a multiparty conference hosted on an external MCU or TelePresence Server, not on the local endpoint.

Multisite is a purchasable option for certain Cisco TelePresence codecs (such as the SX20 and EX90) that activates a built-in internal MCU function, allowing the endpoint to mix and switch video from multiple remote participants. This eliminates the need for an external TelePresence Server or MCU for small multiparty calls, reducing infrastructure requirements.

MeetMe is a CUCM conferencing feature where participants dial into a shared conference number, not a capability embedded in a video endpoint.

Ad hoc conferencing in CUCM relies on an external conference bridge resource, not processing performed locally on the endpoint.
