Regular calls from this number and no real connection or message. I call back and it is a machine indicating "Press any number to be removed from this list. It may take 24-48 hours." I have just set call blocking on my phone. There seems to be an irresponsible entity phishing.
Got 3 calls today from 415-534-9643. Caller ID shows Stinson Beach CA. When I answered, nothing.. then hanged up! If you use iphone, you can block the caller.
