Got a call on October 6th. I didn't answer and no message was left. Caller ID said, "Wireless Caller."
I am thinking that, with elections coming up in November, there are a lot of election related calls happening. They are not necessarily scams or bad things. I simply don't answer my phone. I turned off the ringer and let it go to voice mail. Out of 100 calls, I might get two or three voice mails. Elections will be over in a few weeks.
