Multi-Tech Systems MVP120 - Manual (Page 56)

The Add/Edit Phone Entry dialog box contains two groups of information: 1. Station
Information which contains the phone number, description window which can be left blank,
and the voice channel number. Station Identification group contains the H.323 ID and the IP
Address window for the IP Address of the MultiVOIP assigned the phone number, and the
Port number of the MultiVOIP unit communicating with the Gatekeeper. This port number has
to match the port number pair used by the Gatekeeper. If the port number on either end is
changed, communication between endpoint and the Gatekeeper is lost.
The Station Information identifies the calling unit by the phone number, and voice channel
of the unit doing the calling. The Phone Number does not have to be a conventional
telephone number. It can be a three digit number such as 101. The Description box and the
H323 ID/alias box may contain the same information. It is recommended that the
Description box be left blank and the identifying information be enterred in the H323 ID/alias
window. The voice channel box defines the voice channel associated with the phone number.
The Station Identification group allows you to define the MultiVOIP unit by entering the
H323 ID/alias which can be the same, as for example, your name in your local telephone
book listing. The Gatekeeper associates the H323 ID/alias with the address of the local unit
in the IP Address window. The Port number 1720 is the port of the MultiVOIP communicating
with the Gatekeeper.
The Station Information and Identification of the MultiVOIP unit have to be identical to the
information used by the Gatekeeper in order for the MultiVOIP unit to be registered with the
Gatekeeper. The Gatekeeper can allow an open registration or a secure registration in which
the endpoints are pre-defined by the Gatekeeper. The registration method is determined by
the Gatekeeper administrator and will require communication with each endpoint in order to
develop the H.323 compatible network.
The Phone Directory Database for the local unit holds the local phone numbers, destination
details of the IP address, port number, and channel number of the local unit. The description
is the same as the entry in the H323 ID entry in the Add/Edit Phone Entry dialog box.
