Chapter 5 Configuring the Voice Interfaces
H.323 Gateway Configuration
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 5-19
• ISDN BRI Configuration (H.323), page 5-24
• T1/E1 Configuration (H.323), page 5-31
• E&M Trunk Line Configuration (H.323), page 5-35
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 Catalyst 4224 voice ports.
To configure plain old telephone service (POTS) dial peers, use the following
command strings:
c4224(config)# dial-peer voice number pots
c4224(config-dial-peer)# destination-pattern endpoint#
c4224(config-dial-peer)# port 1/portnumber:DS0groupnumber
Replace:
• number with a unique numeric identifier for each dial peer
• endpoint# with the E.164 telephone extension of the POTS dial peer
• portnumber with 0 or 1, depending on which T1 port you are using
• DS0groupnumber with a numeric digit from 0 to 23 for each DS-0 group you
are configuring
For example, the following commands could be used to route all calls with the
prefix 222 to the DS-0 hunt group 1 of controller T1 1/0:
c4224(config)# dial-peer voice 222 pots
c4224(config-dial-peer)# destination-pattern 222....
c4224(config-dial-peer)# port 1/0:1
c4224(config-dial-peer)# prefix 222
The prefix command at the end is required to replace the digits that the
Catalyst 4224 strips off from the dialed digit string based on the wildcard
destination pattern.
