H.323 Gateway Configuration
Configure H.323 endpoints connected to the Catalyst 4224 Ethernet port.
Step 4
To configure H.323 endpoints, use the following command strings:
c4224(config)# dial-peer voice number voip
c4224(config-dial-peer)# destination-pattern endpoint#
c4224(config-dial-peer)# session target {ipv4:ipaddress|dns:hostname}
c4224(config-dial-peer)# codec codecid
Replace:
•
•
•
If you use the IP address, it must be preceded by the parameter ipv4. If you use
the DNS host name, this must be preceded by the parameter dns, and the host
name must resolve correctly to the IP address of the target. Finally, you must
identify the coder-decoder (codec) used by the Voice over IP (VoIP) dial peer.
For example, the following commands assign extension 2001 to the IP device with
the network address 192.168.100.1:
c4224(config)# dial-peer voice 1 voip
c4224(config-dial-peer)# destination-pattern 2001
c4224(config-dial-peer)# session target ipv4:192.168.100.1
c4224(config-dial-peer)# codec g711u1aw
Step 5 Direct calls using wildcard destination patterns, as needed.
You can use wildcard destination patterns to simplify your dial plan configuration.
For instance, you can direct all incoming calls starting with specific digits, such
as 525, to a Cisco CallManager configured as an H.323 endpoint. You might
direct all calls starting with a 9 to voice ports connected to the Public Switched
Telephone Network (PSTN), or direct all calls beginning with an 8 to a private
branch exchange (PBX).
c4224(config-dial-peer)# destination-pattern pattern ....
For example, the following command directs all calls starting with 525 to a
Cisco CallManager with the DNS host name CCM30:
c4224(config-dial-peer)# destination-pattern 525....
c4224(config-dial-peer)# session target dns:CCM30
