Recd call from this number on my caller id, with no message.  Called the number back and it was a number for a woman @ VTech/Verizon.  She said that it was probably a "test" call and when I asked her if there was a way to have my "unlisted" phone number removed from her call list, she told me no.  This is the 3rd call I have recd from Verizon like this in about a week with a totally different number.
