RCHITECTURE
The LifeSize Multipoint enables both voice-only and video conference calls for
H.323, SIP, H.320 and regular PSTN network telephones. H.323 and SIP
devices can connect to a conference directly through the LifeSize Multipoint.
Other devices such as voice telephones and video conferencing terminals
(H.320) can connect to a conference via a gateway, such as the LifeSize
Gateway.
The LifeSize Multipoint supports devices that can send and receive video
streams, as well as those that cannot send but only receive video streams. This
means that terminals without a video camera or video capturing capabilities can
participate in a conference as voice-only participants while benefiting from
seeing the other participants.
