There's nothing particular to what you're trying to do, just configure the POTS dial peer with the destination pattern you want, and tie it to the port you want the call to go out.
For inbound calls, configure the connection plar to the DN you wish to ring.
voice-port 0/0/2
connection plar opx 4000
dial-peer voice 24 pots
destination-pattern 91[2-9]..[2-9]......
forward-digits 11
port 0/0/2
