Chapter 3 - Defining Network Services

Prefix (cont’) Notes :
• When PathNavigator is used, this prefix
automatically registers with the gatekeeper. When
another gatekeeper is used, this prefix must also
be defined in the gatekeeper.
•
When a firewall is used, two IP Network Services
are usually defined; one for the card that is
connected to the external network and the other
one that includes all the remaining cards (those
connected to the internal network).
Refresh H.323
Registrations Every
n Seconds Enter the frequency in which the system informs the
gatekeeper that it is active by re-sending the IP
address and aliases of the IP cards to the
gatekeeper. (The conference details are not
registered.) If the IP card does not register within the
defined time interval, the gatekeeper will not refer
calls to this IP card until it re-registers. If timeout is
set to 0, re-registration is disabled.
Note: It is recommended to use default settings.
