Voice Over IP (VoIP) Application

The L2W-323 Gateway allows H.320 terminals, ISDN and regular phones to exchange
voice with other H.320 terminals, ISDN and regular phones over an IP network bypassing a
long distance switched network, as illustrated by the following figure:

Figure 7 - Voice over IP communication via Gateways

It is not unusual for companies and corporations today to be dispersed over several
continents. This drastically increases long distance phone expenses and one of the ways
companies are dealing with this growing expense is through Voice over IP technologies.

Using your IP data network for voice communication enables you to utilize your
infrastructure more efficiently. Eventually, you will be able to simplify the management and
upkeep of your communications networks by removing the circuit-switched network and
routing all communication traffic—voice, video and data—over the IP network.
