Chapter 7 - Using the MultiVOIP Software
Gatekeeper Phone Directory Database
With the Gatekeeper Phone Directory Database, the Gatekeeper acts as the central point
for all calls within its zone and provides call control services to registered endpoints. The
Gatekeeper performs address translation from LAN aliases to IP addresses and provides
bandwidth management where the network manager has specified a threshold for the number
of simultaneous calls on the LAN. The H.323 ID is an alias. The Gatekeeper may use other
information as an alias such as a URL or an e-mail address.
When the Gatekeeper Phone Directory Database option is enabled, the RAS Parameters
group is enabled with the IP address of the Gatekeeper displayed in the IP Address box. The
Port Number is the port of the endpoint communicating with the Gatekeeper. If this number is
changed, it should only be changed with consultation with Gatekeeper administrator. The port
numbers have to match with the Gatekeeper.
If the H.323 Gatekeeper network supports Q.931 Fast Start servicing, then the Use Fast Start
option on all endpoints should be enabled. The Call Signalling Port of 1720 is the port on the
MultiVOIP unit supporting the Q.931 parameters.
The Phone Directory Database in a H.323 Gatekeeper network only displays the station
information and station identification of the local unit. The station information and identification
must be entered in conjunction with the Gatekeeper administrator so that the identification of
the endpoint is the same. To add an entry to the Database, click Add. The Add/Edit Phone
Entry dialog box displays.
