I haven't kept up with asterisk, partly because they kept changing the 
apis all the time so it was hard to use it for anything, but I thought 
that even a long time ago someone had it connecting the 'other' way 
through a cell phone - that is to use the cell connection as one of its 
lines.  I'm not sure about about using the dialer and audio side, though.

That was the point of the base station with wireless handsets.  I've 
seen those with 3 or 4 handsets for well under $100.  They are intended 
to be used as house extensions while your cell phone is charging near 
the base.  And at least some take a landline too.
