Kufre,

Check these two things:

1) Check to make sure that the your 2821 IOS is "ipvoice" and not "ipbase".

2) Check to make sure that you have enough on-board DSPs installed to support 4 FXO ports. If there are not enough DSPs the router will not recognize the card.

And as always, show diag and show platform will help as well.
