2 stage dialing plan

i would like to know how to do a 2 stage dialing plan. I have been unable to find any info on how to execute this task with asterisk. I am going to call in on free world dialup and then second stage out on pstn. i have fxo cards and would like to know how to do this with those cards. if anybody has any help on configuring the cards and on 2 stage dialing it would be greatly appreciated.

thanks

here is the info on how to do this kind of thing with your asterisk box if anybody is interested… it is called DISA.
