Received a one-ring at 8:28 this evening. Caller ID said "OPINION RESRCH." Looking it up yielded no information but it WAS clear that all manner of scams have used this phone number (which most definitely means it is spoofed).

10/25/15 @2:24 PM (SUNDAY) (our local: West Norriton Twp, PA) Caller ID: TOWSON, MD called on my landline from #667-308-3710 -- a hang-up AGAIN; how many of these calls do we have to received before something is done; have an unlisted # and both landline and cell are on the "DO NOT CALL LIST".
