10 LifeSize Gateway User Guide
The LifeSize Gateway-PRI 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 LifeSize Gateway allows all IP network terminals to support
video conferences without connecting every desktop computer to an ISDN line
(see Figure 1-1).
