CHAPTER 3: CONFIGURING THE V7122 GATEWAY The V7122 gateway is supplied with application software already resident in its flash memory (with factory default parameters). Section Assigning the V7122 Gateway IP Address describes how to assign IP addresses to the V7122. Section Configuring the V7122 Basic Control Protocol Parameters describes how to set up the V7122 gateway with basic parameters using a standard Web browser (such as Microsoft TM Internet Explorer).
Assigning an IP Address Using HTTP To assign an IP address using HTTP, follow these 9 steps: 1 Disconnect the V7122 gateway from the network and reconnect it to your PC using one of the following two methods: Use a standard Ethernet cable to connect the network interface on your PC to a port on a network hub / switch. Use a second standard Ethernet cable to connect the V7122 gateway to another port on the same network hub / switch.
Assigning an IP Address Using BootP BootP procedure can also be performed using any standard compatible BootP server. You can also use BootP to load the auxiliary files to the V7122 gateway (see the V7122 Digital Gateway User Guide). To assign an IP address using BootP, follow these 13 steps: 1 Open the BootP application (supplied with the V7122 gateway software package). 2 Click on the Edit Clients icon 3 Click on the Add New Client icon (Figure 11).
Figure 11 Client Configuration Screen with Blank Parameters Assigning an IP Address Using the CLI To assign an IP address using the CLI, follow these 7 steps: 1 Enable the Embedded Telnet Server: a) Access the V7122 gateway Embedded Web Server (see Accessing the Embedded Web Server). b) Set the Embedded Telnet Server parameter (under Advanced Configuration > Network Settings > Application Settings) to Enable (Unsecured). c) Reset the gateway.
6 Change the network settings by typing: SCP IP [ip_address] [subnet_mask] [default_gateway] (for example, SCP IP 10.13.77.7 255.255.0.0 10.13.0.1); the new settings take effect on-the-fly. Connectivity is active at the new IP address. This command requires you to enter all three network parameters (each separated by a space). 7 To save the configuration, at the prompt, type SAR and then press Enter; the V7122 gateway restarts with the new network settings.
Accessing the Embedded Web Server To access the Embedded Web Server, follow these 4 steps: 1 Open a standard Web-browsing application such as Microsoft™ Internet Explorer™ (Version 6.0 and higher) or Netscape™ Navigator™ (Version 7.2 and higher). 2 In the URL field, specify the IP address of the gateway (for example, http://10.1.10.10 for the first module of the V7122 gateway); the Embedded Web Servers Enter Network Password screen appears, shown in Figure 12.
The following configuring Sections from here up to and including Configuring Basic SIP Parameters apply individually to H.323 or SIP. H.323 configuring continues with Configuring Basic H.323 Parameters. SIP configuring continues with Configuring Basic SIP Parameters. Once the gateway is configured correctly back up your settings by making a copy of the VoIP gateway configuration (ini file) and store it in a directory on your PC. This saved file can be used to restore configuration settings at a future time.
Enable the DMZ configuration on the residential router for the LAN port where the V7122 gateway is connected. This enables unknown packets to be routed to the DMZ port. 2 When working with a Gatekeeper, under H.323 Parameters, set the Working with Gatekeeper field to Yes, and then enter the IP address of the primary Gatekeeper in the Gatekeeper IP Address field. When no Gatekeeper is used, the internal routing table is used to route the calls. 3 Leave Enable Annex D/T.
H.323 users should continue with Section Configuring the Trunk Settings. Configuring Basic SIP Parameters After accessing the Embedded Web Server (see Accessing the Embedded Web Server) the SIP Quick Setup screen is displayed. Figure 14 V7122/SIP Quick Setup To configure basic SIP parameters, follow these 11 steps: 1 If the V7122 gateway is connected to a router with NAT enabled, perform the following procedure. If it is not, leave the NAT IP Address field undefined.
2 Under SIP Parameters, enter the V7122 gateway domain name in the Gateway Name field. If the field is not specified, the V7122 gateway IP address is used instead (default). 3 When working with a Proxy server, set the Working with Proxy field to Yes, and then enter the IP address of the primary Proxy server in the Proxy IP Address field. When no Proxy is used, the internal routing table is used to route the calls. 4 Enter the Proxy name in the Proxy Name field.
V7122 gateway completes the restart, Ready and LAN LEDs on the front panel are lit green. 10 After the gateway is reset, configure the V7122 gateway trunk parameters. For information about configuring the trunk parameters, see Configuring the Trunk Settings. SIP users should continue with Section Configuring the Trunk Settings. The following sections from here, up to the end of this Guide, apply equally to H.323, and SIP.
