4.2.2 Programming the Address Translation Table
The function of an address translation table in a VoIP network is to provide 2-way translation of telephone
numbers and IP addresses
*1
. Therefore, a caller can reach the destination by dialing the number without
knowing the destination IP address.
The procedure below demonstrates the process of programming the address translation table at the local PBX.
After the address translation table at the local PBX has been fully programmed, repeat the procedure for the
address translation table at the remote PBX with the appropriate setting values.
1.
a. Under Configuration, click Slot.
b. Move the mouse pointer over the small PBX image
for virtual slots.
c. Click Select Shelf.
d. If the V-IPGW16 card’s status light is green, move
the mouse pointer over the card, select Ous from the
menu that appears, and then click Yes on the dialog
box. The status light will turn red.
e. Move the mouse pointer over the installed
V-IPGW16 card. A menu will be shown under the
mouse pointer.
f. Click Shelf Property.
g. Click GW Settings.
2. In the Main tab, do the following to configure the
gateway entry for the remote PBX:
a. In the GW Name box, type a unique identifier of the
destination in the VoIP network.
b. In the GW IP Address box, type the IP address of
the destination gateway device.
c. In the GW Group box, select None.
Note
Having the value None for GW Group means
that the destination gateway device does not
belong to any gateway group. Grouping is useful
when installing multiple gateway devices at one
location. For details, refer to "3.11 [1-1] Slot—
Shelf Property - Virtual IP Gateway—GW
Settings— GW Group" in the PC
Programming Manual.
d. Click OK to return to the Shelf Property screen.

IP address-to-telephone number translation can also be handled by using an H.323 Gatekeeper device. To configure Gatekeeper
devices, refer to the manufacturer’s documentation. This manual focuses on the method using the V-IPGW16 card’s internal address
translation capabilities.
