The seventh phone number with the same area code this week, including 540-605-8982. I've noticed that when I "ignore" the call, whoever it is stops calling. If I'm unable to "ignore" the call, calls continue every two minutes. So far the maximum is three consecutive calls. None of the numbers leave a message. These calls are probably from a spoofed number, initiated by scammers with an auto-dialer. They appear to select an area code within your vicinity or state in order to increase the probability of the receiver answering their calls.
When they call they normally call twice back to back. I haven't answered it yet but I am going to call it back to find out who they are pretending to be.
