I don't understand where you're planning to save money here.  Calls
into a mobile network are free for the caller under any circumstances.

The free mobile-to-mobile deals apply only to the mobile phone user;
if I have it, calls to or from my mobile from other users on the same
network are free to me, but the other party still pays whatever his
plan says.  If your calls aren't placed from a mobile they're free
anyway (or whatever your landline rate is, which should be pretty
close to free) so where's the savings?

If, nonetheless, you want to experiment with this kind of hack, look
for devices with names like cellsocket and dock-n-talk that take a
cell phone and provide a landline interface that you should be able
to connect to a PBX.

R's,
John
