Gatekeeper
The following are the general functions of a gatekeeper:
•
Dialed number-to-IP address translation
•
Authentication
•
Bandwidth control
It is possible to employ a VoIP network without the use of a gatekeeper, because the card is equipped
with internal address translation capabilities. However, should the network contain dozens of cards,
maintenance of address translation tables in individual cards can become a strain.
A gatekeeper is useful in this case, because with the gatekeeper it is possible to consolidate the
maintenance. (However, you still need to program each card on the network with its own address
translation information. For details, refer to "2.2.6 Address Translation Table—GW Entry" and "2.2.7
Address Translation Table—DN2IP Entry".) For more information about gatekeeper functions,
consult the documentation of the gatekeeper.
When using a gatekeeper, make sure to choose a compatible model. For more information about
gatekeeper compatibility with the card, consult a certified dealer.
