Do you have another analog line that's on the same Central office as the
line in question?  The delay could be lag time betwee the time you hang up
your cell phone, the cell provider MTSO processes the hang up, passes it
on to their termination provider, who then passes it on to your
termination provider, who then passes it on to you.
