How Do I Filter Phone Calls on a Land Line? 181
An anonymous reader asks: "I have a telephone on a plain old land-line, with the option of subscribing to caller-id.
I would like to filter incoming phone calls, diverting them to either the handset or answering machine, based on whether the caller-id matches a list of trusted phone numbers.
Considering that many of today's land-line telephone handsets can display caller-id and store a list of favourite phone numbers, I don't think this is technologically difficult.
AI am not interested in: subscribing to a service provided by my telephone company. I would prefer the filtering occurred on my side of the phone line, or implementing a software solution on my PC. Frankly, that is overkill, and I don't want my PC turned on permanently. I would prefer something like a small, solid-state hardware device. Is there any such thing available?"

It should have similar modes controlling whether or not the machine will accept a voice message. That should all be simple to implement in a device that connects like a regular phone (in parallel). When reviewing the incoming calls, it should be a one-touch operation to specify how the machine should handle future calls of the same type.
The super-duper version should have the ability to sit between the phone line and other devices (series) and use a speech synthesizer and recognizer (or dtmf decoder) to allow control from regular phones throughout the house. e.g. A call comes in, the phones give a single short ring as the machine announces itself to the caller. If a person picks up a phone, the machine tells him whatever it knows about the call and asks whether to hangup, connect, or take a message.
Talking Caller-ID (Score:4, Informative)
The Caller-ID information is sent between the first and second ring, so the only way to avoid ringing is to drop the first ring 100% of the time. On the occasions where you do want to talk to someone, the time left to get to the phone is that much shorter.
I have an AASTRA talking Caller-ID box in my house. It does a great job of managing the phone. If the caller has intentionally blocked their Caller-ID information then it automatically answers after one ring and tells them I don't accept blocked calls (which are inevitably from telemarketers) and they should call back with Caller-ID enabled. For the rest, it speaks the phone number so I know who it is before I get to the phone. If it's someone I don't want to talk to then I just let it ring until the answering machine cuts in. It supports blacklisting so that people who annoy me don't even get to leave a message. One interesting feature is that I can record a short audio clip and have it matched to a specific name or number so that it will play that audio clip instead of speaking the number. That's a great help with things like payphones which I will always want to answer no matter what the number is (my telco sends "payphone" as the Caller-ID name).

On the other hand, you might be that pesky asshole I don't really want to talk to. You know, the one that won't shut up, the one I can't possibly end a phonecall with in less than 20 minutes without being rude.
So let's do the math again:
Besides, my time might very well be more important than yours, and probably is. Remember that you're the one picking the time of the call, not me. You time the call to coincide with a moment you're not doing anything important anyway, unless it's an emergency call. Chances are I'm actually in the middle of something. Are you trying to tell me that whatever it is you want to tell me is more important than anything I might be doing at that time?
If whatever you want to tell me is important enough to interrupt my shedule for, it's important enough to leave a message for. If you can't be bothered to interface with a machine for 20 seconds to help me manage my time, I can't be bothered to interrupt my shedule to talk to you.

Telephone Hacking for Fun and Proffit (Score:5, Interesting)
OK, you have a couple of options as I see it.
First would be to set up some kind of PBX. It's a little complex, but it would work. You could use Asterisk (I think that is what it's called) and some hardware (since I think it was designed for VOIP) and do it that way.
The more fun (in my eyes) and complicated way is to build it yourself. You could do this with a PIC micro-controller (or similar). You could put the little box you would make at the phone entry point of your house. When the phone rings you let the first ring through (so you know someone called). Caller ID is transfered between the 1st and 2nd rings so that is when the MCU picks that up. Based on that, it can power a double pole double throw relay. In the normally closed position the phone signals are routed to your house wiring. When a "bad" caller ID is encountered it simply powers the relay switching the phone line from being connected to the phones to the answering machine. Of course the answering machine could be anywhere if you can isolate it's phone jack from the rest (shouldn't be too hard).
Now there are a few little things to take into account here. First is that you may want to generate a ring for the answering machine so that it picks up on the 4th ring (or whatever) instead of the 5th because of the "lost ring". Second is that if you automatically send people to the answering machine unless the right caller ID comes across (i.e. the answering machine is in the normally closed position) then you'll need to make sure you have a way to force the relay to switch. You would want this even if you decide to pick up a call from the machine. When the main wiring is disconnected you could monitor the wiring to see if anyone picks up (you'd have to power it probably) and switch the relay if that happens. That way any time you pick up the phone you will always get the dial tone/caller. Having the relay connect you to the phone line in the normally-closed position is an important idea because you want it to be safe and let you use the line during a power outage.
It'd be a very cool project. You can find bits about how to do it on the web. For example, I once saw something about a guy who built his own TTL PBX. That project (which was rather well documented, as I remember) would be a gold mine for you.
If you do it, make sure to write it up and post it. I'd love to read it and I'm sure others would too.

I like the idea of keeping the phone line connected all the time by default, and it makes some other things easier. That said, I bet you could easily make the circuit to eat that first ring so it doesn't go through to the house wiring. You could eat ALL rings and just re-generate them yourself on the outputs (house and answering machine).
Heck, you could use a voltage comparison to trigger a disconnect so when the phone rang the line is temporarily disconnect for the duration of the ring signal. The the right sized capacitor to absorb the spike that did get through and a transistor to let you turn that feature on and off (so you can let rings through if you want) would probably do it.
As for how to get the data on and off, there are a few ways. You can go the program the MCU way, but that's annoying as you mentioned. You can make the MCU take direction form a serial port so you can program some flash memory that holds the list. But the easiest way is that it's not too hard to interface to a SD card or similar. You can buy very simple devices that let you access them with just a serial line or two. Put the list in a text file with a simple format (first line is the number of entries, after that each line is a valid number, sorted to allow for binary search) and you can update it trivially without having to reprogram and such.
That said, as the parent poster said you could use a Rabbit or some other MCU with easy external access. There are ethernet (often an add on you can buy for another MCU), you could use serial or USB or BlueTooth. Plus there is always the LCD/buttons approach.
Heck, program it with your phone. Pick up the phone and dial a magic sequence (###) or press a button then pick up the phone and you can do simple button combinations to program it. When in "magic mode" press 1 and then a 10 digit number to add it to the list. Press 2 and then a 10 digit number to remove it from the list. Both are confirmed with a simple tone. Press 3 then a 10 digit number to find out if it is in the list or not (one beep yes, two no). You could add other features later this way too. A simple way to turn on/off the filter for when you are expecting a call but you don't know who it will come from, or you want to go into "silent mode" to watch a movie where EVERYTHING goes to the machine.
You could do other fun stuff. If someone calls from a blocked number and gets the machine, you can monitor that with the PIC. If you detect they press the magic button sequence (44666, spells "HI MOM") then the PIC generates a ring on your phone. This could be used for emergencies. Then you just pick up and the auto-detect I mentioned earlier connects you and you take over from the machine.
The only complication I can see is the issue of how to handle call waiting, but you can avoid that just by turning it off.
I gotta say, the more I write about this the more fun it sounds. Too bad I have no use for it or time to work on it right now.

You can also set up speed dial keys for any combination (#1 on my phone gets you Abo's Pizza in Lafayette.)
I suggest that you keep an actual non-wireless phone plugged into one of the other landline ports in the house -- even if you're on a UPS, a protracted power outage could end up leaving you with no way to call 911. Having an old non-wireless phone around is the safest thing to do -- they draw voltage off the phone line to work, and that usually stays up. Just make sure you don't have to plug the phone into anything other than the phone line and you'll be good to go.
