I just received a call from an unknown number, I decided not to answer it, as I was a little suspicious. Does unknown number mean they doctored it, or what? I really can’t tell if it was a legit customer, a salesman, or a competitor spy.
Would you answer calls that said “Unknown Number” on a business phone?
I’ve also had voicemail messages left from unknown numbers, they were either hangups, or a long silence.
