Chapter 7 - Using the MultiVOIP Software

Changing the Phone Directory Database

The MultiVOIP provides two phone directory database architectures; the propreitary database and a database using an H.323 protocol gatekeeper that provides a centralized call control center. The gatekeeper centralized call control center contains the phone directory database when all VOIP gateways and endpoints support the H.323 protocol. The proprietary database is based on a master and slave relationship in which the master VOIP maintains the phone directory database and distributes it to its slave VOIPs. The centralized call center handles call control, call routing, address translation from LAN aliases to IP addresses, and bandwidth management. The H.323 protocol allows other third party gateways and end points that support the H.323 protocol standards to participate in the VOIP network (e.g., Microsoft NetMetting® ).

The database displays the phone numbers in numerical order with destination details (IP Address or H323 ID \ alias), channel assignment, and a brief description of the entry. The method for changing the phone directory database is dependent on whether the Gatekeeper option or the Proprietary Phonebook option is enabled.

If the GateKeeper option is enabled, the RAS Parameters group is enabled and the IP address of the GateKeeper needs to be enterred in the IP Address window. The Port Number is the port on the GateKeeper which it communicates with its endpoints. The Q.931 Parameters group is enabled in both the GateKeeper and Proprietary Phone Book Database architectures. The Use Fast Start option is used when the VOIP network supports Fast Start capability.

In the GateKeeper phone directory database, the phone directory database is developed through the Add/Edit Phone Entry dialog box. The Add/Edit Phone Entry dialog box defines the Station Information, phone number and voice channel of the unit, and station identification, H323 ID / alias which defines the LAN alias and the IP address of the local unit. In the GateKeeper phone directory database, only the phone entry of the local unit displays.

If the Proprietary PhoneBook option is enabled, the Database Type group is active which defines the Master and Slave relationship. If the database type is master, then the Add, Delete, Edit, Hunt, and Print buttons at the top of the database dialog box are active. This allows the master database to build the phone directory. You can click Slave Status to view the status of the slave units.

The Add/Edit Phone Entry dialog box for the Proprietary PhoneBook is used to add, delete, and edit entries. This information displays in the Phone Directory Database dialog box.

If the database type is set to slave, then the IP address of the master MultiVOIP needs to be entered in the Master IP Address window, the Send Status Report to Master option can be enabled, and all the buttons at the top of the directory database dialog box become inactive, except for the Print button.
