(347) 502-2591

This works; I saw a blog entry of someone else also getting calls from 347-502-25xx (last 2 digits varies). He figured out how to stop the phone calls and it worked for me; either call 307-223-0458 or send an email to service@callerhelp.org; give the caller's phone number (to verify the do not call request will be effective) and your receiving phone number (to remove it from the caller's list) and it'll stop the phone calls.
