Interconnect the devices as shown in the diagram above. Notice that we are using the two FXS ports on the router to simulate the connection to the PSTN. 2. In this step we are going to configure the voice gateway. Refer back to the “Configuring Inter-Cluster Trunks” lab for instructions on how to configure the Fast Ethernet Interface; Basically assign an IP address to the interface and bring the interface up to an operational mode. Also, from the fa. interface configuration mode add the following command which will configure the 26xx router as an IOS h323 voice gateway device: (config-if)#h323-gateway voip interface 3. To check on your voice gateway configuration, exit to privileged mode and use the following command on your router: #show gateway Document the output: ___________________________________________________________ ___________________________________________________________ ___________________________________________________________ 4. In this step, we are going to register the h323 voice gateway with Cisco CallManager. Go to Devices  Gateways  Add a New Gateway. Select the gateway type to be h.323 2 of 7 wyousif Click on the Next button and populate the following fields: Device Name: Enter the IP address of your router’s fast Ethernet interface. Description: Voice Gateway Device Pool: Default Calling Party Selection: Originator Calling Party Presentation: Allowed When done update the configuration page then reset the device. Go back to the “Find and List Gateways” page and make sure that the new gateway shows up. 5 of 7 wyousif Code clause. Leave the value of all remaining clauses at default. When done, click on Insert then Reset the Device. Go back to the “Find and List Route Filters” Page and make sure that the filter is listed. 9. In this step we are going to assign the filter we have created to the 9.@ route pattern. Go back to the route pattern configuration page and select Local_Calls_Only in the “Router Filter” field. When done click on Update then Reset. 6 of 7 wyousif From the IP phone or the CIPC phone dial the PSTN local number (4075821312). Was the call successful? _________________ From the IP phone or the CIPC phone dial the PSTN long-distance number (14082991000). Was the call successful? _________________ Why? ___________________________________________________________ From PSTN phones try to dial one of your company’s phones (IP phones). Were the calls successful? ______________ Why? ___________________________________________________________ 10. In this step we are going to configure the h.323 gateway to route calls originating from the PSTN to your company. Go back to your router and type the following commands from global configuration mode: dial-peer voice 100 voip destination-pattern 40769..... session target ipv4:172.168.Pod#.100 Notice that this configuration is needed for direct inward dialing. From a PSTN phone, call one of your company’s phones (dial 40769+LDN). Was the Call Successful? _______________ Why? ___________________________________________ 11. In this step we are going to configure Calling Party Transformations. Go to Devices  Phones  Find and List Phones. Select the IP phone and from the Phone configuration page select Line 1. In the “External Phone Number Mask” filed type 40769xxxxx. When done, click on Update. Go back to the route pattern configuration page and under the “Calling Party Transformations” section, make sure that the “Use Calling Party’s External Phone Number Mask” is checked. When done click on update then reset. 7 of 7 wyousif Go to Devices  gateways  Find and List Gateways. Select the h.323 gateway. In the “Calling Routing Information – Inbound Calls” section, specify the number of Significant Digits to be “5”. When done update the configuration and reset. 12.Test the configuration by making a call from a PSTN phone to one of your company’s IP phone. Was the call successful? ______________ Examine the debug output for the last call and answer the following: a. What was the matched Peer? _________________________ b. What is the calling number? ____________________________ c. What is the called number? _____________________________ Also, look at the LCD of the IP phone and examine the calling and called number during the call.
