Started getting calls from this number a couple of days ago. My phone allows me to block incoming calls, and I recommend it highly. It's so satisfying to hear that one short ring followed by "Caller Blocked" on my phone's screen. What these callers hear is one blip of a ring, then the busy signal, and then they are cut off!!! If your own phone won't block calls, check with your local phone company. It's the only answer. These dirt bags may or may not give up right away, but they don't get through.
