Your phone number was probably in use before by someone else. When someone cancels their account, I think the phone companies leave the number idle for awhile, but then assign it to someone new. I don’t know what that time period is - someone here who works/worked for phone companies can probably provide a knowledgeable opinion. So, you are either getting auto-dialed, or the call was for the former user of your phone number. Either way, you are safe to ignore it.
Not all phone systems support it. I think you need dual-ring capability. The call rings your phone and nomorobo’s phone at the same time. If nomorobo thinks it’s a spammer, it picks up from it’s end and your end is disconnected.
I’ve used it for a while and the only ‘disadvantage’ is that your phone still rings one time. Other than that I haven’t had any problems.
I’m surprised an enterprising VOIP provider hasn’t integrated nomorobo into their service natively already. They could first send the call to nomorobo and then send it normally if nomorobo doesn’t take it. That would avoid the first ring going to your house.
In any case, many VOIP providers offer dual-ring capability. Depending on your phone needs and internet speeds, you may be able to get everything you need for less than $10/month.
What a coincidence - I got a call from the IRS (USA’s version of the tax office) telling me that I was under investigation and needed to call some phone number in Washington - not Washington, DC, where the IRS is actually located, but Washington state, on the other side of the country (about 5000 km away, I think).
This is about the fourth time I have gotten one of these (far more common are the “Windows Technical Support” callers who try to make me think there’s a problem with my computer, then want access to it, almost certainly to upload some ransomware onto it and then demand hundreds of dollars to restore access to my computer). It sounds like they’re getting their act together now; in the past, the calls came from the “Department of Criminal Affairs.”
Yes. Their whole purpose is to steal as much money from gullible people as they can. After my dad suffered a traumatic brain injury, he was defrauded of $15,000. Fortunately the credit union was on the ball and wrote it off as fraud.
