Topic: Blocking incoming calls. (Read 354 times) previous topic - next topic


Hello, I get calls to my house from random long distance numbers that call about 5 times a day and just ring once. I have call display and know the numbers but I can't block theme because my phone doesn't have that feature.

What I want to make is something that get's the phone number of the person calling and pick up and hang up if they call, I know how to do this in software but I'm just not sure how I can connect my arduino to the phone system and get the number.. and not explode from the mas amount of voltage that goes thought the phones...

Any suggestions?
