Has anyone incorporated a cell-phone chipset into a project?  I would
like to give one of my projects the ability to place a cell-phone call
(to play recorded audio - not data), but I don't have the foggiest idea
where to start.

I thought of simply buying an interface cable and plugging into an
existing cell phone, but I'd rather use whatever chipset a cell-phone
uses instead of buying an existing cell-phone.

Has anyone done this before?  Anyone recall a magazine article?  Thanks!
