One report on 800Notes from last summer claims it's a debt collector, but gives no name. The calls are most likely automated and being abandoned, which the FCC tolerates not more than 03% of the time. Meanwhile, the FTC gives you a handy tool in the form of the FDCPA for quieting collectors.
For many call categories you're best off sending a cease-comm notice via USPS Certified with return card. This will set a legal landmine, as such a notice is ignored at their peril. Of course, this depends entirely on discovering a caller identity, and this caller is playing peekaboo long after your sack time. You may have little choice but to return the call when convenient and demand some answers.
By the by, while charities have DNC exemption, the commercial fundraisers most of them hire don't share the umbrella. Those call centers must add your number to an internal no-call list on request, and are subject to fines for noncompliance.

This number keeps calling, and calling, and calling - they leave no message, and if we DO answer, there is nobody there and just a "click" at the other end.
Originally I'd thought it was campaign recordings, but I'm not so sure now. Our primary was last Tuesday. We shouldn't be receiving anymore calls. AND, these idiots call LATE - all of them after 8:30 pm and right up to the last second until 9. Yes, I know they are allowed to call until 9 my time, but we go to bed by 8 because we have to be up by 3:30 am.
Short of shutting the phones off - which I can't do because I have children and elder parents - I wish I had a virtual bazooka mounted inside my phone that could actually blow those idiots' phones up at the other end. I'm sick and tired of being harassed and DO NOT CARE if they are allowed to call me because they are a charity or campaigning. They are HARASSING ME. If I have money to donate, I'll call THEM. And I've told every single one I actually have spoken to that if they call again, I WILL NEVER DONATE AGAIN. PERIOD.
