Yes it's possible. Simply a matter of dial-peers. Related reading:

Here's an overly simplified config example. There are many additional command options but this gets the ball rolling:
!The FXO port
voice-port 0/1/0
!Where you want the router to direct incoming calls
connection plar opx 1234
caller-id enable
!The FXS port
voice-port 0/2/0
station-id name Example
station-id number 1234
dial-peer voice 100 pots
destination-pattern
port 0/1/0
dial-peer voice 200 pots
destination-pattern 1234
port 0/2/0

Hello,
Thank you Jonathan for your tip.
I had done a test but unsuccess. I don't know why but my Interface FXO seems no detect the ring pulse because when into a call from my PABX to the extention it's pluging in that FXO nothing happen.
I think there is some tuning to do at the configuration about ring, pulse, etc. but I don't know where neither how to
any tip about how to tuning that it's welcome.
thanks

My problem is when the call come from of extention 21 ( FXO ) to extention 2000 ( FXS ) of course numer dialer is 20 ( number of extention PABX ) but nothing happen on router A. when I turn on debug nothing appear! I Think should shows anything on console but nothing. so I wonder what is happen ?
When the call come from FXS interface to FXO it's work!

Hi,
Please capture the following debugs on both routers for the not working call:
deb voice ccapi inout
deb vpm signal
deb h225 asn1
Do "term mon" and/or "logging console" and capture the output.
