Help with a simple setup

Hi,

I have an Asterisk server setup at home with a X100P card connected to a PSTN line. When a user called in from the outside, I heard 2 rings and the asterisk system kicked in and played an announcement. The announcement asked the user to press 0 for the operator or 1 for the IVR system (this works fine up to this point). If the user pressed 0, I want it to dial the analog phone connected to the X100P card (this does not work). If the user pressed 1, then the IVR systemm kicked in (this works). How can I make asterisk dial back to my PSTN phone? Any help would be appreciated.

My Dial plan:

exten => s,n,Answer
exten => s,n,Wait(1)
exten => s,n(begin),Noop
exten => s,n,Background(custom/intro)
exten => s,n,WaitExten(5)
exten => 0,1,Dial(DAHDI/g1)
exten => 1,1,Playback(custom/welcome,noanswer)
exten => 1,n,Goto(custom-enterProdid,s,1)
