1.5 Applications

Here are some examples of how you can use your ZyXEL Device.

1.5.1 Make Calls via VoIP Service Provider

In a home or small office environment, you can use the ZyXEL Device to make and receive
VoIP telephone calls through a VoIP service provider.
The following figure shows a basic example of how you would make a VoIP call through a
VoIP service provider. You use your analog phone (A in the figure) and the ZyXEL Device
(B) changes the call into VoIP. The ZyXEL Device then sends your call to the Internet and the
VoIP service provider's SIP server (C). For PSTN phones (E), the VoIP call server forwards
calls through a trunking gateway (D). For IP phones (F), the VoIP call server forwards calls
through the Internet.
