Where to Go Next
At this point, you should make sure that Cisco CallManager is properly configured to provision the voice
gateway and to configure MGCP endpoints or H.323 route patterns as required. Refer to the
documentation and online help provided with Cisco CallManager. Refer to the Cisco IOS software
configuration guide and command reference publications for more advanced configuration topics. For
troubleshooting information, refer to the system error messages and debug command reference
publications.
Access these publications on the Documentation CD-ROM that came with your gateway, or on the World
Wide Web from the Cisco home page.
H.323 Gateway Configuration
Compared to Media Gateway Control Protocol (MGCP), H.323 requires more configuration on a
gateway because the gateway must maintain the dial plan and route pattern. The gateway must have
enough information to direct calls to the correct end point, which must be an H.323-capable device.
When using H.323, ensure that you configure Cisco CallManager correctly to provision the AGM as an
H.323 gateway, with route patterns configured to route calls to a AGM.
To provision the gateway using Cisco CallManager Administration, select the Add a New Gateway
option from Device > Gateway. Assign the Gateway Type as H.323 Gateway, and the Device Protocol
as H.225.
To configure a route pattern using CCM Administrator, select Route Plan > Route Pattern and enter
the route pattern. Then select Cisco Catalyst 4000 AGM from a drop-down list, click the Route this
option button for the Route Option, and check the Provide Outside Dial Tone box for Offnet (the
default is OnNet).
To configure a specific interface or line signalling type, see the appropriate section provided later in this
chapter. In general, you need to perform the following steps to complete H.323 configuration.
Step 1 Identify the port number and enter line-specific information provided by your local carrier, as described
in the following sections:
Configuring T1-CAS Analog Emulation (H.323), page 5-14
ISDN BRI Configuration (H.323), page 5-17
T1/E1 Configuration (H.323), page 5-22
Step 2 Configure parameters for the voice interface you are using, as described in the section referred to above.
Step 3 Configure H.323 endpoints connected to the AGM voice ports.
To configure plain old telephone service (POTS) dial peers, use the following command strings:
gateway(config)# dial-peer voice <number> pots
gateway(config-dial-peer)# destination-pattern <endpoint#>
gateway(config-dial-peer)# port 1/<portnumber>:<DS0groupnumber>
