How Do I Filter Phone Calls on a Land Line?

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?"

I did RTFP, and I don't give a fuck what you want. Asterisk will do what you want, and a PBX is the only way to go unless you just want to let you phone ring until the answering machine comes on, or you get off you lazy ass and read what your caller ID displays. Now go suck a cock, and be grateful for the useful answers you get. Just because the answer you want to hear doesn't exist doesn't give you the right to get snappy at the people who help you out. Now go drink bleach you selfish pig.

Yet you quoted from it, and replied only "read it yourself".
