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.
