My other question is whether or not Verizon will expand the number of handsets beyond 4? We would like to add an ADDITIONAL 4 handsets.

(We can figure a way to add one more by taking the base unit handset to another location and using the base as a speaker phone only. But we cannot find a charger base sold separately and do not want to pay for another handset just to get a charger.)

But we still would like to buy another 4 handsets if they would be supported.
