Programming the Address Translation Table
The function of an address translation table in a VoIP network is to provide two-way translation
of telephone numbers and IP addresses
*1
. The address translation table is owned jointly by all
VoIP Gateway Cards in the network. Therefore, whenever the address translation table is
changed, it is important to update all the cards in the network with the latest information;
otherwise VoIP communications cannot be established.
It is possible, at one location in the network, to program the address translation table that
contains information for the entire network. The completed address translation table can then
be distributed across the network, so that all the cards share the same information (see "4.2.6
Downloading the Address Translation Table from the VoIP Gateway Card", and "Uploading
Address Translation Table to the VoIP Gateway Card" in "4.3 Programming the VoIP Gateway
Card in the Chicago Office").
The procedure below demonstrates the process of programming the address translation table
necessary for VoIP communications between the Los Angeles and Chicago offices.
The specific setting values are based on the table under "PBX Connection Information" in
"1.2.2 Numbering Plan Example".

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 VoIP Gateway Card’s internal
address translation capabilities.
