Something about add multipoint call at local display?

Multiway is a separate Cisco feature that escalates an existing call to an external Cisco TelePresence Server or MCU for multipoint processing - it does not handle the multipoint display locally on the endpoint itself.

Multisite is an embedded multipoint conferencing capability built directly into Cisco TelePresence and Room Series endpoints, enabling multiple participant video streams to be composed and displayed on the local screen without routing through an external infrastructure device. It is licensed per endpoint and processes the multipoint layout locally, making it the correct answer for enabling multipoint display at the local device level. This contrasts with solutions requiring external servers or bridge infrastructure.
