It doesn't. These scammers use dialers and if you answer or push any buttons, they will just call more. ROT is to not answer. And they do need reported, they can be reported here:

Consider buying a call blocker also, either device or phone.

This number has called my house several times in the last 5 days. I am so over it. It doesn't matter what anyone says or does these unwanted calls just keep coming. I swear I think the DNC list sold our information to the telemarketers.

This number is a telemarketer. They break the law by calling numbers regisitered on Do Not Call. When I told them that, they said they never heard of such a list, and then DEMANDED that I "SHUT UP AND LISTEN" (those EXACT words). Their Tel-Com carrier is Bandwidth Communications. They will investigate such abuse of their lines. File a complaitwith them here:

This number is used for illegal telemarketing purposes. They call numbers that are on the Do Not Call registry. They claim to have "never heard of such a list". When I asked them to remove me from "their" call list, they demanded that I "SHUT UP AND LISTEN" those were their EXACT words. The number is owned and issued by Bandwidth Communications. They are not the ones placing the calls, they only issued the number. Bandwidth will is very cooperative in shutting down such operations, and compllaints to them will be investigated.

The person who is making calls is a convicted pedophile.  He hangs up if an adult answers.

I'm in California with a 619 area code.  This number shows on my caller ID as a local number in Jacumba, CA, BUT, my phone has a special ring for long distance calls and this call was definately not local.  It's what is called a "local long distance call". Something new the spammers have latched onto.

calls I never answer and they never leave a voicemail   who they are don't know  

Just got a call saying Hello Mr. _______? Somehow they knew my last name. I just kept asking them "why are you calling me" . After doing that about 3 times as I never verified my name, they hung up.

With The Panasonic KX-TGA470 phones I have, I can set up a call block list.  Love that feature.

This number called and hung up. I called back phone was busy.

Third time this week, after saying hello 3 times a guy comes on the line wanting to talk to me about home improvement or something, I told him it was the third time in a week that someone from that number called and I was getting a little tired of it.  He claimed he never called before, but would put me on their do not call list.  Let's see what happens.

Spoofed phone number and location. This is a foreign boiler room full of scumballs trying to steal your money.  Yell at them and hang up. Asking them to stop calling is a waste of time.

Foreign caller from Jacumba asking for me as Mr."First name" bad connection and hung up. Bad

This is from a company called Kiwi energy - it's a scam and I called SDGE to tell them as they open up with how you can save energy using them.  I hate them and have used At&T u verse to forever block them.  They # comes up as: UNKNOWN CALLER

I have been getting so many calls and I am on the Do Not Call List.  Most calls and do not leave a message.
ASIA Pacific 971-208-9936 calls a lot.  I do not answer.  I saw when I checked their # here "whocallsme"
someone said do not answer but press # key and that is suppose to stop them from calling. I

I don't even answer this number any more, but I sure wish SOMEONE would bust them for making calls to those on the DNC list!

Caller ID says Jacumba.  Called yesterday and left no message.  Called again today and the answering machine picked up.  The caller didn't realize that it was an answering machine and said "hello (my name)".  He hung up when he realized no person was speaking to him.

Called today on Oct 1 at 10:27 AM. No message left. Did not answer unless identifies self. Ignored call.

Got a call from this number.  It's from Jacumba, CA.  When asked to identify herself, the caller hung up.

Got a call from this number today..no message...glad I have caller ID - Jacumba, CA.

Got a call from this number.  No message left.  I refuse to answer calls from an unknown phone number.

Picked up, no one on the other side.

Kept calling telling me I was authorized a discount on my electric bill.  I told them not to call yet they repeatedly called me back.

Called me at 418 today and left no message. Call from Jacumba CA.

Called and left no message. Have been getting MANY calls like this for months.

These a***oles called just now, I told them we weren't interested and I'd asked them before to take me off the call list, he said "shut up, shut up" and clicked. Never call my house again a***oles, next time you are getting a call from lawyers.

This number called my home phone repeatedly last night. The caller would hang up before I could answer, and subsequent calls resulted in no message left. I tried calling it several times today and only got a busy signal. Obviously a spam caller.
