Programmable device to block calls based on Caller ID?
Is there a programmable devices that I can hook up to my phone line to selectively block certain numbers e.g. block by area code, block by last 2 digits of the phone number, etc. I once had an old modem that provided the Caller ID number in a register, and I could determine what to do with the call based on the area code.
