4.4 Setting Up a VoIP Phone with H.323
You can use the ZyXEL Device to manage calls from your VoIP enabled phone using H.323.
The following diagram shows an example of a VoIP phone configured to make calls over the
Internet.
Figure 28 Tutorial: H.323 Phone Setup
To configure your ZyXEL Device to allow VoIP phone calls using your H.323 phone, you
need to set up the H.323 ALG (Application Layer Gateway) and port forwarding, which in
turn requires a fixed IP address for your phone.
IP Address Settings
Follow these steps to give your phone a fixed IP address.
1 Click NETWORK > LAN > Static DHCP to open the Static DHCP screen.
2 Type the MAC address of your device in the MAC Address field and a valid IP address
