Configuring the Cisco AS5800 as an H.323 Gateway

•Use the show dialplan number command on the local and remote routers to verify that the data is configured correctly on both.

•If you have configured number expansion, use the show num-expcommand to check that the partial number on the local router maps to the correct full E.164 telephone number on the remote router.

•If you have configured a CODEC value, there can be a problem if both VoIP dial peers on either side of the connection have incompatible CODEC values. Make sure that both VoIP peers have been configured with the same CODEC value.

Use the debug voip ccani inout command to verify the output string the router dials is correct.

Use the debug cch323 rtp command to check RTP packet transport.

Use the debug cch323 h245 command to check logical channel negotiation.

Use the debug cch323 h225 command to check the call setup.

Configuring the Cisco AS5800 as an H.323 Gateway

The Service Provider implementation of Voice over IP uses both gatekeepers and gateways. Because of the extensive capabilities of the Cisco AS5800 universal access server, it is likely that it will function as a carrier class gateway in a Service Provider environment. The final step in configuring the Cisco AS5800 for Voice over IP functionality is to configure one of its interfaces as a gateway interface. You can use either an interface that is connected to the gatekeeper or a loopback interface for the gateway interface. The interface that is connected to the gatekeeper is usually a LAN interface—Fast Ethernet, Ethernet, FDDI, or Token Ring.

To configure a gateway interface, perform the following steps beginning in the global configuration mode:

Step

Command

Purpose

1

Router(config)# gateway

Enables the gateway.

 

 

 

2

Router(config)# ip cef

Enables Cisco Express Routing.

 

 

 

3

 

Configure the interface. This step will vary, depending on

 

 

the interface you select as being the interface connected to

 

 

the gatekeeper. For the purposes of this procedure, a Fast

 

 

Ethernet interface is used.

 

 

 

4

Router(config)# int fa0

Enters configuration mode for the configured Fast

 

 

Ethernet interface connected to the gatekeeper.

 

 

 

5

Router(config-if)#h323-gateway voip interface

Identifies this interface as a VoIP gateway interface.

 

 

 

6

Router(config-if)#h323-gateway voip id gatekeeper-id

Defines the name and location of the gatekeeper for this

 

{ipaddr ip-address [port-number]multicast}

gateway.

 

 

 

7

Router(config-if)#h323-gateway voip h323-id

Defines the H.323 name of the gateway, identifying this

 

interface-id

gateway to its associated gatekeeper.

 

 

 

8

Router(config-if)h323-gateway voip tech-prefix prefix

Defines the technology prefix that the gateway will

 

 

register with the gatekeeper.
