8 Only one Gateway? - Click Yes if the NBX system has only one H.323
gateway system.
CAUTION: Multiple gateways must have unique configurations. Multiple
gateways need a distinguishing "Gateway Number". Assign the first
installed gateway to number 0; the second to number 1; and so on.
3Com recommends that licenses be allocated equally when using
multiple gateways.
9 Enter the Call Processor MAC Address. To find it, log on as an
administrator in the NBX NetSet utility, and click Reports, followed by the
System Data tab.
Be sure to record the Call Processor (NCP) MAC Address, not the
Music-On-Hold MAC address, which also appears in the System Data tab.
10 Select the country in which you are using ConneXtions. This defines the
tones and cadences that ConneXtions uses.
11 Specify the UDP and TCP port ranges for use with a firewall. If these
ranges are not important in your system, use the default settings. You can
coordinate these settings with the firewall administrator.
12 Do you want to interface with a Gatekeeper? Click Yes if you want to use
a gatekeeper. Gatekeepers act as the central point for all calls within their
zones and provide call control services to registered endpoints.
13 If you have chosen to use a gatekeeper, enter the IP address of the
preferred gatekeeper. This forces ConneXtions to try to use this
gatekeeper first and provides a more secure option. If you want
ConneXtions to autodiscover a gatekeeper, leave the field empty. You
might chose to do this if you only have one gatekeeper on your network.
14 Choose what you want ConneXtions to do if it cannot register with the
preferred gatekeeper:
Autodiscover a new Gatekeeper — ConneXtions allows you to make
direct H.323 (unregistered calls) while attempting to contact an
alternative gatekeeper on the network.
Continue unregistered — ConneXtions continues to function without
using a gatekeeper.
Block Calls — ConneXtions blocks calls if it cannot register with a
gatekeeper. (You must either have a gatekeeper on the network, or select
one of the other options which enables ConneXtions to work without a
gatekeeper present.) If a gatekeeper becomes available, you must stop
the ConneXtions service and then restart it.
