hhmm, I wonder how long it takes here for that to happen.
You cant turn a cell number into a landline nor viceversa.

Heck, most providers dont even like it when you install a
gsm gateway to call your coworkers for free with the
gateway.

So here it's pretty simple to know wether a call is to
landline or cell.
