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.
