The Cisco IPVC 3500 Series Gateway supports multimedia conferencing by translating between H.323
and H.320 protocols. Examples of network applications that use the gateway include:
•
Multimedia conferencing (See the
“About Multimedia Conferencing” section on page 1-16
)
•
Point-to-Point conferencing (See the
“About Point-to-Point Conferencing” section on page 1-17

“About Multipoint Conferencing” section on page 1-17
)
About Multimedia Conferencing
The Cisco IPVC 3500 Series Gateway enables H.323 endpoints on the IP network to communicate with
an H.320 terminal, an ISDN phone, or a regular phone on a circuit-switched public network without
having to connect directly to these networks. The gateway allows all IP network terminals to support
video conferences without connecting every desktop computer to an ISDN line (see
Figure 1-7
).
