Smivs writes "The BBC report on a new gizmo that can block/filter spam phone calls. The system basically intercepts all calls. If it recognizes them as a friend or a member of the user's family — numbers on the so-called star list created by the user — it lets them through as normal.
If the caller's number is on a zap list — numbers of telemarketers or other nuisance callers — the device answers it, and all future calls from that number, with an automated message which means the phone does not ring at all.
If the system doesn't recognize the caller's number, or the caller withholds their number, it asks them who they are, puts them on hold and then rings the user's phone.
The user has the option of taking the call, having the system take a message, or they can reject the call and add the number to the 'zap' list.
Users can add callers to their 'star' list by pressing the star button on their phone at any point during a call." So wait, they can't spam me twice? If I press a button? And if they actually show their phone number on my caller ID? What about the auto insurance scammers that hit me 10x/week?

Hey, we could use that in the U.S. too (Score:5, Interesting)
The only criticism that I have is that it rings my phone at all (for an unrecognized number). I would prefer a system where an unknown caller (those not on the white list) has to first identify themselves as a real person (by keying some numbers) and then leave a message. The phone should only actually ring for whitelisted callers, everyone else should have to prove themselves human for the privilege of leaving a message.
The most annoying calls now are the "robo-calls." What really infuriates me about them is that I can't seem to hang up on them (if you try to hang up and pick up the phone later, the message is still playing). This pisses me off because it means that my phone company is somehow in cahoots with these bastards and is essentially letting them hijack my phone line without my permission. What if I needed to make an emergency call and had to wait for the robo-call to go through all its "great offers" before I could even dial out?

This would be a great option for it, however it could be looked at as annoying for the caller. The reason I got rid of my land line when I moved is because of all of the telemarketers, robo-calls, etc. It got to the point where I wouldn't answer unless I recognized the number anyway. If it was an important call, they would probably leave a message anyway.

I've been using Vonage for quite awhile now, signed up for the do not call registry, and if I don't recognize the number or it is not shown, I simply do not answer. Life has been much simpler doing that.

VoIP is definitely the way to go. we really shouldn't need to purchase/install another device just to have automated control over our phone line. seems like with an open VoIP standard and an open source VoIP handset, you could just program such behavior directly into the phone. there's really no need for special hardware.
the other thing to do is regulate cold-calling (whether commercial or political/non-profit). force all automated cold-callers to be registered in an online database. when you receive a cold call, the caller will send you its number/ID that your VoIP phone will automatically look up on the online database and handle the call appropriately (e.g. hang-up/block all commercial calls, or take a message if it's a non-profit caller and save the voice message to a special inbox).
VoIP systems can also be easily extended. for instance, you can require anonymous callers to enter a password that you'd only give out to friends. that way if a friend needs to reach you from an anonymous line they can still get by your call filter. you just can't do this type of thing with traditional cellular or landlines because they're on proprietary networks.

I've always dreamed about such a device, basically a little captcha for the phone. I work from home and get tons of robo calls, and even if it's not a robot talking on the phone, marketing firms usually have some machine dialing the call and then hand it off to someone once the machine determines there's a human on the line. Ever wonder why you say hello and it takes the person on the other end a few seconds to respond? That's why. Phone captcha would eliminate these calls... at least for awhile until someone beats the captcha.

Buy a Telezapper.
http://www.telezapper.com/ [telezapper.com]
When you (or your answering machine) picks up the phone, the telezapper plays a dialtone.
Humans just hear a tone, auto-dialers interpret it as "this line has been disconnected"
I got one for my parents, long before the Do Not Call list and after around a month, as your number gets taken off of auto-dialing lists, it makes a huge difference in the volume of calls that come in.
You can also do it, like I did for myself, by recording the tone [astreet.com] onto the beginning of an answering machine message, but the telezapper works whenever you pick up the phone. So if you're fine with letting every "unknown number" go to the answering machine (my parents were not) you can implement the Telezapper's $40 functionality for free.

I do this on my Asterisk system by having an answering machine on my POTS line give out an 0870 (expensive to call) number that forwards to my VoIP phone number. My friends and family have the real number (so don't pay the 0870 call rate). The ringer is switched off (as is the speaker) on my answerphone so I don't hear it ring, it doesn't disturb me and the call spammers don't generally like to call 0870 numbers. It's a win-win. :)

I write robo-call software and when something like that happens it is the fault of your local carrier. Many of the local carriers in the US have been getting lazy about sending the proper signals when a connection is disconnected. It is up to the carriers to send this signal. I can regularly call my boss' landline and get a difference of 30 seconds between when he hangs up and when I finally get the signal has been disconnected.

But the ones that really irk me are the "lower your credit card interest rates" that I get every few days, and it's different caller id each time. Usually falsified caller id. So I would still end up getting about the same number of nuisance calls.
What would be optimal would be the FCC doing their job and shutting the scammers down, but I'm not holding my breath.
Re:Partially useful (Score:5, Informative)
First of all, don't EVER give money to these "firefighters" and/or "police" charitable funds. Many, many scammers pose as these charitable organizations, and they only want your credit card/checking account info. Also, even if such a charity is legitimate, there's no reason to fund their administrative costs, money that doesn't go to the police or firefighters, money that pays for them to—you guessed it—make more telemarketing calls.
If you want to support your local firefighters and/or police, call them and tell them that you'd like to make a donation. I assure you that they will be more than happy to accept your kindness, and best of all, they will make use of 100% of the money you donate, not pay people to bother yet more people by making unsolicited calls.
Second of all, you're missing part of how this gadget works. If you're not on the whitelist or the blacklist, you'll be asked to say your name. It then rings your line and tells you what the name of the person is who is calling. Or, at least, what they recorded as their name. At that point, you can either answer, whitelist them, or blacklist them.
I suppose your phone might still ring, which could be considered a nuisance, but you're never actually talking to the idiot who is calling you, and there's a measure of satisfaction knowing that they're getting a message that says something like, "This person is refusing to take your call. Have a nice day!"

That's the problem I would have. Probably more than half of the calls I get that are unlisted are calls that I want. The other half are telemarketers. Even though I am on the "Do Not Call" registry, they get around it by either:
a) Pretending to get the wrong number, hanging up quickly when I call them on it.
b) Have some loose (and yes, sometimes legitimate) connection to a "Not for profit and Tax Exempt" business which, at least in Massachusetts is enough for the registry to not apply
c) Is a survey related to some business connection I have. Credit Card companies who sold my info etc.
None of these three are calls that I would pick up, but I just don't see this device weeding them out. I suppose if this device could "answer" then ask for a name, and instead of ringing, play the recorded name... otherwise hang up. That would be good.

I see every unsolicited call as an opportunity. If I am in a hurry there are a number of quick responses.
The "National Security drop number" is a good one. You sound agitated and ask them what their security clearance is. When they don't understand you say "this is a top secret number - hos did you get this?". Whatever they say you then become really calm and say "O..K.. don't worry. Just stay on the line and we will soon have this resolved". Move the phone away from your mouth and ask "how is the trace going.... good". They usually hang up really soon.
Another good one is to ask them for their number so you can call them back. Say you never trust anyone unless you made the call. Some actually will give you a number, which you pretend to write down but ignore
Another is the "sexual interest". This takes a little longer, because you have to start by listening as normal. After a bit you say something like "you know, you sound really hot. Do you live anywhere near (somewhere a long way away)?". If they don't hang up then you can start asking what they are wearing, etc. This works really well for other men, they usually can't wait to get off the line. (I wouldn't go to far, I don't think anyone would try to prosecute you for harassing them when they made the call, but stay legal)
Then there's the "in the same line of business". This can actually be used for a quick call, but its best to wait until they finish. Note down a few points then respond with something better. "Actually I work for associated life insurance, and whereas you can guarantee 4% growth I can offer you a policy that will guarantee 4.2%, plus with a discount on the first six months premiums.
Another one is to listen all the way through and then decline for a really illogical reason. They are well rehearsed at the "can't afford it", "already have an alternative" and so on - but "well I would really love too. But you are called Acme associates. I'm afraid that is just incompatible with my star sign. Especially when you call on a Wednesday"
There are plenty more but you get the picture. They are giving you an opportunity for fun.
