11 Chapter 1 - Introduction and Description option. You can not mix the Proprietary PhoneBook with the Gatekeeper. If you choose the Gatekeeper option, interoperability is less of a concern and you can communicate with other third party endpoints that support H.323 (e.g., Microsoft Netmeeting). (2) If you choose the Proprietary PhoneBook, you establish a master-slave relationship in that the master MultiVOIP maintains the phone directory database. All of the phone numbers are listed in the data base so that if you want to communicate with someone in your VOIP network, you can see the phone number in your data base. Everytime you bring up your MultiVOIP the current phone directory is downloaded to your MultiVOIP. The Gatekeeper is a separate application that can operate on a network pc and provides all the controls needed to create, control, and manage an H.323 network zone. The H.323 network zone is all the endpoints (terminals and gateways (MultiVOIPs)) that register with the gatekeeper. The gatekeeper functions are address translation from LAN aliases for terminals and gateways to IP addresses as defined in the RAS (Registration/Admission/Status) specification. The RAS Protocol defines the communication with a gatekeeper and support for RTP/TRCP for sequencing audio packets. The H.323 Gatekeeper also provides call-authorization for both accepting and placing calls in its zone, handles hunting (call-rollover), and certain monitoring features (i.e., call permissioning and address resolution). So, if you choose the Gatekeeper option, initially you need to communicate with the administrator of the Gatekeeper to preregister your MultiVOIP. The information you need from the Gatekeeper administrator is the IP address of the Gatekeeper and its port number. Then you need to establish your alias address which includes phone number, channel number, H323 ID which is a name, e-mail like address, etc, and your MultiVOIP LAN IP address. The port number is 1720, but if the Gatekeeper uses a different port number, you have to ensure that you use the same port number. The Gatekeeper administrator will then enter your information into the Gatekeeper data base. This concludes the preregisteration. Now, you can enter your alias address information into the Add/Edit Phone Entry dialog box. For example, if you were setting up the corporate MultiVOIP, you could enter the following information for Voice Channel 1. For instance, in our typical application channel 1 of the Corporate MultiVOIP uses extension 101. The Description is optional, but can be helpful if it is assigned to a particular individual or department, or in this case it defines the channel interface. The H323 ID that was assigned to this phone number is an e-mail like address which identifies the individual that is using this extension and the domain name of the Gatekeeper (in this example corporatehd). The IP Address of the Corporate MultiVOIP is 201.022.122.118 and the default port number 1720 is used. So now when you “come alive”, the Gatekeeper will register you with the above alias address. No other H323 endpoint can use this alias. This is like your own telephone number. Now, if you choose the Proprietary PhoneBook option in the Phone Directory Database dialog box instead of the Gatekeeper option, the Database Type group would become active and the RAS Parameters group is inactive (greyed out).
12 MultiVOIP 400/800 User Guide Now, lets 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 there phone numbers. Lets again use the corporate MultiVOIP and we will set up the database so that the corporate MultiVOIP can call the sales, marketing, or regional offices. To do this, the Phone Directory Database will have four entries for the corporate office, and two entries for the sales office, two for the marketing office and two for the regional office. Extension 101 at the corporate office is tied to voice channel 1, 102 is tied to channel 2, etc. The Description again ties to the type of interface used on the corporate MultiVOIP (E&M). The Hunt Group in this situation is set for No Hunt. But if you wanted to activate a Hunt Group, i.e., 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, say 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 data base, 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 entries for each office. The proprietary data base would then appear as in the following dialog box and when the office MultiVOIP is turned on, the current data base would be down loaded.

18 MultiVOIP 400/800 User Guide Installing Your MultiVOIP The basic steps of installing your MultiVOIP 400/800 network involve unpacking the units, connecting the cables, and configuring the units using management software (MultiVOIP Configuration). This process results in a fully functional Voice Over IP network. A general description is provided below and detailed instructions are provided in Chapter 3, Software Loading and Configuration. Installing and Configuring Your MultiVOIP The VOIP administrator must first install the MultiVOIP 400/800 software and then configure each MultiVOIP 400/800 for its specific function. During the configuration process, it’s important to note that the Phone Directory Database is configured differently depending on whether or not you have Gatekeeper support on your VOIP network. If your VOIP network supports Gatekeeper software, you must pre-register or remotely register all H.323 endpoints with the Gatekeeper. The procedure for doing this is explained in the section “Registering with a Gatekeeper Phone Directory.” If your VOIP network does not have Gatekeeper software or the Gatekeeper software is not enabled, then you must build a proprietary phonebook with a “Master” MultiVOIP and “Slave” MultiVOIPs. The “Master” unit includes the assignment of a unique LAN IP address, subnet mask, and Gateway IP address; as well as the selection of appropriate channel interface type for each of the Voice/Fax channels. Once all connections have been made, the VOIP administrator configures the unit and builds the Phone Directory Database that will reside with the Master unit. Once configuration of the “Master” MultiVOIP has been completed, the administrator moves on to configure the MultiVOIP(s) designated as “Slave” units. Again, unique LAN IP addresses, subnet masks, and Gateway IP addresses are assigned, and each Voice/Fax channel is configured for the appropriate channel interface type. When this is done, the Phone Directory Database option is set to Slave, and the IP address of the Master MultiVOIP is entered. Once all Slave units are configured, the process moves on to the “Deploying the VOIP Network” section. Deploying the VOIP Network The final phase of the installation is deployment of the network. When the remote MultiVOIPs are sent to their remote sites, the remote site administrators need only to connect the units to their LAN and telephone equipment. A full Phone Directory Database (supplied by the Master MultiVOIP Proprietary Phonebook will be loaded into their units within minutes of being connected and powered up. For remote VOIPs that were configured with the Gatekeeper option enabled, each MultiVOIP will be remotely or pre-registered with the Gatekeeper (i.e., the Gatekeeper phonebook directory is NOT downloaded to the remote units). The final task of the VOIP administrator or the Gatekeeper administrator is to develop the VOIP Dialing Directory based on the appropriate phone directory database (i.e., the Proprietary phonebook database or the Gatekeeper phonebook database). Safety Warning Telecom 1. Never install telephone wiring during a lighting storm. 2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations. 3. This product is to be used with UL and cUL listed computers. 4. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface. 5. Use caution when installing or modifying telephone lines. 6. Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote rist of electrical shock from lighting. 7. Do not use the telephone to report a gas leak in the vicinity of the leak. 8. To reduct the risk of fire, use only No. 26 AWG or larger telecommunications line cord.

Cable Connections 3. Connect the MultiVOIP to a PC by using a DB-25 (male) to DB-9 (female) cable. Plug the DB-25 end of the cable into the Command port of the MultiVOIP and the other end into the PC serial port. See Figure 2-2. 4. Connect a network cable to the ETHERNET 10BASET connector on the back of the MultiVOIP. Connect the other end of the cable to your network. 5. If you are connecting a station device (e.g., analog telephone, fax machine, or Key Telephone System (KTS) to your MultiVOIP, connect one end of an RJ11 phone cord to the Voice/Fax Channel 1 FXS connector on the back of the MultiVOIP and the other end to the station device. If you are connecting the station side of a telephone switch (PBX) to your MultiVOIP, connect one end of an RJ11 phone cord to the Voice/Fax Channel 1 FXO connector on the back of the MultiVOIP and the other end to the phone jack. If you are connecting an E&M trunk from a telephone switch to your MultiVOIP, connect one end of an RJ45 phone cord to the Voice/Fax Channel 1 E&M connector on the back of the MultiVOIP and the other end to the trunk. Refer to Appendix B for E&M cabling pinout. If you are connecting to an E&M trunk, you need ensure that the E&M trunk jumper is in the correct position for the E&M type trunk. The default E&M jumper position is E&M type 2. To change the E&M jumper position, perform the E&M jumper block positioning procedure. 6. Repeat the above step to connect the remaining telephone equipment to each Voice/Fax Channel on your MultiVOIP. 7. Turn on power to the MultiVOIP by placing the ON/OFF switch on the back panel to the ON position. Wait for the BTG LED on the MultiVOIP to go OFF before proceeding. This may take a couple of minutes to go OFF. Proceed to the next section to load the MultiVOIP software.
