It's a spoofed VOIP number. The technique is used by debt collectors to make repeated calls intended to annoy people they are trying to collect debts from. It's illegal. (Making the calls from the debt collector's real number would subject them to penalties of collections laws that prohibit harassment.) So they use throw-away cell phones or spoofed numbers to make the annoyance calls. Source: Ex-boyfriend worked for a bill collector and used this technique to harass me after we broke up. The calls can be traced. My ex did 120 days jail time for his little stunt after he was caught.
I don't owe anyone money and I'm receiving these calls. I don't think it's debt collector related. They calls probably have to do with the upcoming election.
You may not owe anyone money. But your phone number may have belonged to someone who does (or is alleged to). Or, your name is similar to theirs. Or, is the same or similar to someone used as a credit reference or co-signer. Political pollers are also not likely to use VOIPed 'dead' landline numbers'.
