About Multimedia Conferencing

The Cisco PRI 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 1-1).
