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.

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 

on your LAN in the IP Address field. In this example the MAC address is 
00:A0:C5:00:00:02 and the IP address is 192.168.1.33.

3 Click Apply.
