1.1.2 VoIP Trunking Gateway

VoIP trunking allows you to use your ZyXEL Device as a gateway between VoIP and PSTN networks.

Figure 2 ZyXEL Device as a VoIP Trunking Gateway

In this example, you use your analog phone (A) to call the ZyXEL Device (B). The ZyXEL Device changes the call into VoIP and sends it via the Internet to another VoIP phone(C).

1.1.3 ZyXEL Device’s Router Features

Your ZyXEL Device provides shared Internet access through your existing Internet access gateway (company network, or your cable or DSL modem for example). Computers can connect to the ZyXEL Device’s LAN ports (or wirelessly).

You can also configure firewall and content filtering on the ZyXEL Device for secure Internet access. When the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network. This means that probes from the outside to your network are not allowed, but you can safely browse the Internet and download files.
