Save router configuration with write command.Type in exit to leave configuration mode.Enter exit to leave dial peer configuration mode.Configure the signalling protocol with session protocol sipv2.Enter session target with session target ipv4:10.1.2.2 command.Enter a destination pattern with destination-pattern 9.T command.Type in dial-peer voice 9 voip command to create another dial peer.Specify the codec to be used when establishing a session through this dial-peer with codec g711ulaw.Enter session target with session target ipv4:10.1.1.10 command.Enter a destination pattern with destination-pattern 14085552… command.Type in dial-peer voice 14085552 voip command to create dial peer.Enter exit to leave interface configuration mode.Type in h323-gateway voip bind srcaddr 10.1.1.101 command.Enter interface configuration mode with interface FastEthernet 0/0 command.Enter exit to leave Voice over IP configuration.Type in allow-connections sip to h323 in order to enable SIP to H.323 communication.Type in allow-connections h323 to sip in order to enable H.323 to SIP communication.Type in voice service voip command to enter into Voice over IP configuration.Type in configure terminal to access the configuration mode.Open a telnet session to the router Site 1.
In this task we will configure both routers as a H.323 voice gateways controlled by Cisco Unified Communications Manager. Task 2: Configure a voice gateway for Cisco Unified Communications Manager controlled H.323 SIP Trunk Both router are listed as a H.323 gateway in Cisco Unified Communications Manager.You have completed this task when you attain these results: – Device Name: 10.1.1.102 (the IP address of the H323 Gateway connected to the Voice LAN) Repeat steps 1 – 5 for the second router with the following parameters:.Now the IP address of the H323 gateway will appear.Click Reset button, and another Reset button.– Uncheck Wait for Far End H.245 Terminal Capability Set – Device Name: 10.1.1.101 (the IP address of the H323 Gateway connected to the Voice LAN) On the Gateway Configuration page, use the following parameters:.For gateway type, select H.323 Gateway, and click Next.On Cisco Unified Communications Manager Administration page, from the menu select Device > Gateway and click Add New.In this task we will add both routers as an H.323 gateways to Cisco Unified Communications Manager. Task 1: Add a H.323 Gateway to Cisco Unified Communications Manager However, in the recent time there are more and more implementations of SIP trunks between the CUCM and the Voice gateway, sometimes referred as Cisco Unified Border Element (CUBE). In general the Cisco Unified Communications Manager supports two major types of gateways based on the protocol being used to control them – Media Gateway Control Protocol (MGCP) and H.323 gateways. Cisco Unified Communications Manager and Cisco gateways use a variety of TDM interfaces, however the supported TDM interfaces may vary based on the gateway generation. Trunk interfaces specify how the gateway communicates with the PSTN or other external devices by using time-division-multiplexing (TDM) signaling. The Voice Gateways are used for call termination when the internal IP Telephony infrastructure has to communicate with the PSTN and other non-IP telecommunications devices, such as private branch exchanges (PBXs), key systems, analog phones, fax machines, and modems. Cisco Unified Communications Manager supports several types of Cisco Unified Communications gateways.
