Multitech MultiVOIP 100 MVP110 User Manual page 11

Chapter 1 - Introduction and Description
The H323 ID assigned to this phone number identifies the office that is using this extension. The IP
Address of the Corporate MultiVOIP is 201.022.122.118 and the default port number 1720 is used.
Once the MultiVOIP goes online, the Gatekeeper registers it with the above H.323 ID. No other H323
endpoint can use this H.323 ID. This is like your own telephone number.
If you choose the Proprietary PhoneBook option in the Phone Directory Database dialog box
instead of the Gatekeeper option, the Database Type group becomes active and the RAS
Parameters group becomes inactive.
Now, let's change the typical application to not have the Gatekeeper control the call session. When
you elect to use the Proprietary PhoneBook, you set up a master-slave relationship. This relationship
allows one MultiVOIP to maintain the Phone Directory Database and publish this data base to all
MultiVOIP participants in the network. This proprietary data base allows you to see all the
participants in your network and provides you with their phone numbers.
Let's again start with the corporate MultiVOIP and we will set up the database so that the corporate
MultiVOIP can call the remote branch office and the remote branch office can call the corporate
MultiVOIP. To do this, the Phone Directory Database will have two entries for the corporate office and
two entries for the Remote Branch Office. Extension 101 at the corporate office is tied to voice
channel 1. The Description again ties to the type of interface used on the corporate MultiVOIP
(FXO). The Hunt Group in this situation is set for No Hunt. But if you wanted to activate a Hunt
Group (if an extension on the MultiVOIP is busy and you wanted to look for another extension), you
can assign a hunt group to those extensions. So that, if extension 101 is busy, the corporate
MultiVOIP would roll over to extension 102.
Again, the IP Address of the corporate MultiVOIP needs to be added and the port number is 1720.
This adds phone number 101 of the corporate MultiVOIP to the proprietary data base. Now, to add
extension 102 to the proprietary database, all you have to do is change the Phone Number and
Description to support channel 2 of the corporate MultiVOIP. After you have added channel 2, you
need to include the two channels at the remote branch office.
