Not seamless unless the cell phone provider offers such a service.  You 
won't find that available in the US.  So even though it's one phone, 
you'd have 2 numbers.  Cell phone providers have no incentive to offer 
such a hand-off because they wouldn't make any money on the calls after 
they are handed over to the voip system.
