Changing IP Parameters
The IP Setup dialog box establishes the IP addressing for the local Ethernet LAN, defines the Internet
gateway address, and for a remote MultiVOIP the global-to-local IP address translation is defined on
the Proxy Setup tab. The IP Setup dialog box is accessed by clicking the IP button on the MultiVOIP
200 Setup menu.
When the IP Setup dialog box is displayed, the IP address of your MultiVOIP is displayed with its IP
Mask. The Gateway Address is the IP address of the device connected to the Internet. This
completes the fields in the IP Protocol Default Setup dialog box.
ProxyServer
The Proxy Setup tab is used when a ProxyServer is used to connect the LAN to the Internet. The
Proxy Setup dialog box is displayed by clicking the Proxy Setup tab in the IP Setup dialog box.
If a ProxyServer is used in a MultiVOIP network, an address translation takes place within the
ProxyServer to direct the phone call to the correct MultiVOIP.
When a MultiVOIP’s connection to the Internet is through a ProxyServer, the WAN port on the
ProxyServer must have a static registered IP address. Remote MultiVOIPs will only be able to
access a MultiVOIP located behind a ProxyServer at the static IP address. This static IP address will
be used in the Phone Directory Database when assigning directory numbers to this MultiVOIP.
The Global IP Address field in the Proxy Setup dialog box must contain the static IP address of the
WAN port of the ProxyServer. The Local IP Address field in the Proxy Setup dialog box must contain
the local IP address of the MultiVOIP. In this case the local IP address is not used in the Phone
Directory Database. There must be a unique static IP address on the Wan side of the proxy server for
each MultiVOIP located behind the proxy server.
