I get a call from this number, 918-570-5402, almost once a day, sometimes twice, and this has been going on for months. I never answer my phone anyway, unless I recognize the number or my caller id identifies them as someone I know. They never leave a message, and whatever automated system they are using knows to hang up before the answering machine engages. The caller id only identifies the phone number and that it is a Wireless Caller.I am on the DNC registry as well, and I can tell you that as long as I keep it updated it works - you do have to go back to DNC and re-register your phone numbers after a certain amount of time. I do not get calls from legitimate companies anymore. However... I am not sure that DNC can do anything about sneaky companies that use cell phones to do their dirty work.
