The Cisco PRI gateway and BRI gateway enable 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
