Step 2
section referred to above.
Configure H.323 endpoints connected to the Catalyst 4224 voice ports.
Step 3
To configure plain old telephone service (POTS) dial peers, use the following
command strings:

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.
