Use one of those fax/modem/phone sharing boxes that blocks the other

Set the primary unit to pick up on, say, 2 rings and the secondary unit 
to pick up on 4.
If the primary fails, it won't pick up the line and the secondary takes 
over.

You could try having your phones register to both but I'm not sure how 
that would work
