As usual, it's not that complicated, and it's not that simple.

The simple solution would be for the network providers to validate the caller ID numbers for its subscribers, but that requires changes to punish the ones that don't do it.

I've worked with telephony for 15 years and I know the big providers do this for most common telecom protocols, but VoIP providers tend to be more lax. But that's where they shouldn't, and the ones that break this shouldn't be allowed on the network.

I use Robokiller on iOS -- it screens the calls and answers spam with prerecorded scripts paced to match response times and then sends me the recording of the interaction.

What strikes me with robocalls that leave messages - they cut off by "talking" too early so I cannot identify who they are, yet if I answer, I get nothing but silence if I answer with "Hello? Hello?" Calm and slowly paced. That's my personal rule. I say hello slowly twice, and if theres silence, I hang up. Dont care if I start to hear a connection as I'm going to hang up. You called me, have someone on the line. My t…

I generally don't answer any number that's not in my contacts. If I don't know who it is they can leave a message or I'll look up the number and block it proactively.

I've solved the robocall problem personally, by simply not answering my phone.

I'll answer the call if I'm expecting one, if it's from someone who has texted me that they're going to call (this covers 99% of the legit calls I get), or if it's from one of a very tiny number of people who might call me due to an emergency.

Otherwise, it goes straight to voicemail and (thanks to Tasker) doesn't even make my phone ring.

I'd like to know how you don't receive spam calls to your mobile # as the robo-dialers just go through the entire list of phone numbers in that area code, so you have to receive some to that device. I do the same as you but with Skype instead of GV, but my mobile # gets hosed by robo-dialers.

Because while it's a common assumption that the spam callers do this, they don't actually do this, because while robocalling is sometimes illegal, actually dialing every single number removes any/all plausible deniability if they're ever caught, and provides little/no additional benefit.

> Because while it's a common assumption that the spam callers do this, they don't actually do this

It sure looks like they do. Spammers have been calling our office lines daily (including numbers that aren't assigned to anyone and aren't given out). The spam calls come in numerical sequence. They're clearly just working through every possible phone number, in sequence.

I have had a Google Voice number since it was Grand Central. It has gone on all of my business cards. It's at the bottom of every email. I put it on my website. Google does an amazing, world class, mind blowing, job of filtering out robo calls. I get maybe one a week at most. I get more calls direct to my cell number from random call bots that hit every number with mobile carriers than I do through my Google Voice nu…

> Android users have no excuse for not using Google Voice.

You mean aside from not being OK with using Google services?

It's funny how one a week is acceptable in the USA. If I got one a week here I would consider myself getting spammed into depression.

It's not acceptable in the USA.

I'm actually hoping that robocalls are the downfall of the PSTN and big telcos. They are immovable monsters and have outlived their reign in this world.

Except when we provide you 4g and 5g coverage, ensure societies have working critical infrastructure to communicate peer to peer and in addition gives you a nice fiber pipe to your house and handle all the carrier dealings of broadband interconnectivity. Oh yeah and tie this all together with advanced roaming deals and functionality which connects countries around the world. It's also us who pioneer and really implem…

> Telecoms are far from all that bad.

Speaking of US telecoms, they are simply awful and abusive companies. Yes, they provide a critical service, but they sure do take their pound of flesh for it and constantly engage in activities that are harmful to society.

I don't get that many robocalls anymore after I signed up for https://www.donotcall.gov/ . I also make a point of reporting unwanted calls there too (I got two pretending to be from the IRS saying that I was about to be sued). I know that people find it annoying to go through the process of reporting the call, but I consider it to be one of those things that fall under the "All that is necessary for the triumph of ev…

I think that this is the first time I've ever heard someone say that donotcall.gov was effective. I know for sure that it isn't for me.

It's great that the DNC has worked for you, unfortunately it's not much help for me since all my robocallers are criminals trying to steal from me. Naturally, people unafraid of being arrested for fraud are unafraid of DNC fines. I've been on the DNC for years, and a couple years ago I decided to change my number, since my old one was getting 4-5 robocalls per day, always from different numbers.

That sounds horrible. I wonder if there is a way to surrender that number to the FBI, so that they could investigate further. Even one call every other day would be too much to report manually for me in terms of effort.

> I wonder if there is a way to surrender that number to the FBI

The number reported by caller ID is entirely meaningless and not useful in terms of investigation. They just spoof random ones from your area arbitrarily.

Because "that number" is generally fake. Caller ID became meaningless once VOIP was allowed to spoof it. Can we build a new system atop ANI?

> Because "that number" is generally fake. I'm not really convinced this is true, because there are numbers that are categorized as robocallers, and there are others that aren't. You'd think that if they were fake then they'd be random/uniform.

> You'd think that if they were fake then they'd be random/uniform.

They're arbitrary, not random. They switched to that from the old system of just spoofing 000-000-0000 or similar, as people blocked those.
