3.2 Programming the VoIP Gateway Card in the Los Angeles Office

3.2.5 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 . 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 programme 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 "3.2.6 Downloading the
Address Translation Table from the VoIP Gateway Card", and "Uploading Address Translation Table
to the VoIP Gateway Card" in "3.3 Programming the VoIP Gateway Card in the Chicago Office").
Note
The address translation table created for the KX-TDA0490 can be shared with the KX-TDA0484
and KX-TDA3480.
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".
*1 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.
