1.4.3. Voice over IP
The WipLL system enables customers the flexibility of migration from a data-only
network to an integrated Voice-over-IP and data network. The WipLL voice solution
provides interoperability with any IP-to-PSTN network gateway. The use of the IP-
to-PSTN gateway allows operators seamless PSTN connectivity such as SS7
(signaling network), G3-303, and V5.2 over E1, allowing deployment in multi-
national markets.
Figure 1-7 shows a typical WipLL application for VoIP.
