ONFERENCING

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

).
