Did not answer.  No message left on machine.  Let me guess...another telemarketer/scammer.  Sigh.

Got a call from this number. But didn't answer the phone. Answering machine picked up but no message was left. Caller ID came up as injured america. Another telemarketer? Or maybe scam?

Didn't answer...they did not leave a message...looks like another scammer!  so blocked immediately.

If you don't answer and talk to them, you'll never know who they are or what they want...

If you don't answer or allow them to leave a message, they'll assume your number is blocked or isn't working. They'll move onto some other number and leave you alone after a while. Also, they're less likely to pass your numbers onto other scammers. That last statement is debatable as I keep getting calls from new numbers. For example, this number was a first-time caller. So far, I have 11,368 numbers in my blocked list and new ones are added every day. In answer to your post, who cares what they want - they don't have anything legitimate to say.

Unfortunately that's not true any more. Even if you don't pick up (and your answering machine doesn't pick up) as soon as your phone displays the "name" part of their Caller ID it means your phone has submitted an inquiry into the CNAM lookup database. At that point they know it's a working number. Again, this happens even if you don't pick up.

That's really neat information and I don't doubt that it's accurate. My software is really good at detecting new nuisance numbers so I'll just have to take spiritual comfort in knowing that I'll never know who it was that called, or what they wanted.

"So far, I have 11,368 numbers in my blocked list ..."
Have you really gotten that many calls or do you add numbers that others have reported?

I'd say second one

Yes, TheRealSeriously is correct. However, it's a bit more complicated than that. I block most area codes and some geographical regions in their entirety based on my experience of where calls shouldn't come from. That actually covers 95% of the country. The 11,368 represents the exceptions to my white-list. For example, as I live in Nevada, I white-list the entire 702 area code. Most of the 11,368 numbers represent 702 area code numbers I have to block individually. Where do those numbers come from? They were derived programatically from crawling the Internet looking for keywords such as "scam", "telemarketer", "robocall", etc. I also add the government's list of abusers in the white-listed area codes.

That's an...interesting way of doing it, to be sure. I rarely get calls (guess I'm just lucky) so it's easy to add numbers to my block list-then again, I'm not one to just give my number out to anyone. If your system works for you, that's great-glad you found something that works!

Unfortunately for me, my number used to be a 24/7 hot-line when I was in business. Since I retired, I just use it for personal calls. I can get up to 15 nuisance calls a day. Why not just change the number? 1) Because I shouldn't have to - I'm not the one breaking the law. 2) I paid a lot of money for that number and I like it. 3) I enjoy watching the bad guys get hung-up on. 4) I get to add my experience to sites like 800notes without having to listen to the call. 5) It's become an enjoyable hobby to outsmart the bad guys.

I would estimate that my program is >99.9% effective. The only way to make it more effective would be to use IVR hardware to announce something like: "If you want to leave a message, please enter 481356", put them on musical hold for a while, then run them through a long menu chain of Q&A to determine the purpose of the call.  At this point it's not worth the time and money to do that.

There's another reason why changing your number can be a bad idea-you would most likely get someone's OLD one that they got rid of for some reason. Then you'd be dealing with people looking for whomever had the number before you.

Not true! If you answer, it lets them know it's a working number and they will keep calling. If you don't answer or block the number, the person or robo  call will give up. I don't answer any calls from numbers that I don't recognize

Caller left no message.

If the caller hears a ring sound on their end, regardless of whether or not you answer, it is indicated as good.  A bad number doesn't ring.  The system that called doesn't know "blocked", it only knows good and that's indicated by a ring.  It will call- forever, until someone or something answers.

Aside from that, what are you afraid of?  You answer and the caller rapes your cat?  Answer it.  Find out who they are and what they want, don't just keep posting "unknown caller, no message left".  Better yet, get a good callback number, put it in your war-dialer and call them back, every 10 seconds for weeks on end.  Let them complain to the Feds, see how it works out for them.

That being said, this is a "phishing" call.  It's only purpose is to find good numbers, indicated by a rigning sound, blocked, or not.  It will be followed up with up to many dozens of calls from "Legal Help Center" that will try to scam personal info from you.  Recent scams have been for blood thinner medication and IVC filters.

Answer those too.  Give them bogus info.  Have fun, entertain yourself at their expense.  THey only know what you tell them and only the average idiot would go out of their way to allow themselves to become a victim.

Personally, I look forward to these calls, it's too easy and way to much fun to enjoy them at the callers expense and it aloows me the opportunity to pay them back 10,000 fold.

Regretfully, I must marked this "Call type" as "Unknown" since "Well Known Medical Scam" isn't an option.

"If you answer, it lets them know it's a working number and they will keep calling."

If it "rings", whether a ringer on your end or a ringing sound on the callers end, whether anything answers or not, they know it's "working".

"If you don't answer or block the number, the person or robo  call will give up."

That just means you didn't answer.  They'll call back at a time that is more likely to result in an answer, for example, 5 or 6 in the morning.  If it rings, the caller doesn't know if it's blocked or not, they just know it's good, which keeps the number in the system to continue to call at different hours.

"I don't answer any calls from numbers that I don't recognize"

Why would anybody?  Let the unknown caller leave a message.

It amazes me the extent to which people allow themselves to be controlled by the sound of a ringer.  Reminds me of an experiment done with dogs over a century ago.  Yes, people are as ignorant and dogs were over a hundred years ago.

Precisly as others stated before, it's no more than a "phishing" call, that is, one to determine if your number is valid as indicated by a ring sound on the callers end, rather than the tones and recording associated with a disconnected number.  Now that your number is indicated as good, you'll get the next call in line with this scam, one from "Breast Cancer" with a CID number of 240-245-9501.

"Why not just change the number?"

Let's find out...

1) Because I shouldn't have to - I'm not the one breaking the law.

No, but you are getting nuisance calls- Dummy.

2) I paid a lot of money for that number and I like it.

Is the value worth more than the nuisance?  Dummy.

3) I enjoy watching the bad guys get hung-up on.

And all the other guys that aren't "bad".  I bet they like it too- Dummy.

4) I get to add my experience to sites like 800notes without having to listen to the call.

Your "experience" may not even be legit- Dummy.

5) It's become an enjoyable hobby to outsmart the bad guys.

You haven't outsmarted anyone yet- Dummy.

What we have here is a dummy (dummy) that paid good money (dummy) for someone else's (dummy) old number (dummy) so he can hang up (dummy) on everyone (victims) rather than 1) Get a number that doesn't receive so many invalid callers (dummy), 2) Not answer the phone (dummy), 3) Let his answering machine field al his calls (dummy).  There's a word for people like that- "Dummy".

I agree w/Never Acknowledge, THEY are scammers regardless of what THEY are showing on the caller id.  I feel that any legit business would leave a message and just not keep calling.
