I turned on anonymous call reject due to calls where no one said anything.
the next, got this one at the same time of day....shows unknown with this number - no message left- I think it is the same caller
something wrong with my IP address, thick Indian accent, and frankly, a little belligerent...when I asked what company they represented, they said windows technical services ( not microsoft) I told them not to call back, they also called on 210-280-8487....The 0540 came up on my caller id as NOVATEL. 2nd number came up San Antonio TX
