I have always been amazed at the phone scams being perpetrated and telemarketers in general. Over the past month or so, I have been seeing in my CDR, Flowroute CDR and to ensure no one is getting past my firewall, the Asterisk logfiles, 19282244507 trying 2 to sometimes 6 times a day. It either just times out since no one hits an IVR number or extension and now that I have it blacklisted it just hangs up.
What I can't figure, is why these guys keep trying the same numbers over and over again without gaining anyone's attention! 800notes.com and similar sites have this number as a scam number but there is not much other info as apparently no one ever speaks.
Is this just a constant attempt to glean active telephone numbers? Why must they keep on trying? I rarely, if ever, get bothered by such things but I am bugged about the multiple daily dial of my number by the one mentioned above.
Does anyone have a hypothesis on what they are doing or trying to do?
