We this was the darndest thing.
We usually ignore this number as it displays as Phoenix AZ and we have no clients or employees in that state.
Today our Exec Admin was called on her direct line (as they must have reached her via the staff directory). Her name is very similar to the IT Directors and she gets a lot of stupid sales call that were aiming for him simply because they hit the first name result that they're given.
She answered and asked how she could help.
A male voice (undefinable accent) replied with, "Hi (her name)."
She replied with, "Hi, how can I help."
The male voice again replied, "Hi." and then hung up on her.
So I'm guessing, going on the reviews of you fine people, that it was a crappy sales call, some imbecilic newbie got flustered and hung up. Although, if it was a sales call, when your call is actually answered by a person you'd think they'd launch into their spiel.
Caller let the phone ring once and they hung up before I could answer. They are confirming it's a live line and I know these scammers will call back again soon.
