I am looking for something I can build or buy. I have soldering experience with electronics and thats about it. Heres the project: I am looking for something to pick up my phone and disconnect it on the first ring. Here is how its gonna go I have telemarketers and other unwanted people calling my house. I am gonna buy this caller id device called caller id manager and it also has an addon that will attach to a phone line and any call that comes through thats not on my allowed calls list will get sent to this line. So the device that I am wanting will be on that line and any call that comes through will just automatically pick up the line and disconnect it. It seems simple enough but i don't know where to begin. I know certain answering machines will play an announcement and then disconnect but I can't find one that has this option. Any help is greatly appreciated thanks
