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.
