- imp builds a list of people that you want to speak with. When those people call, your home phone rings. Simple as that.
- Whenever anyone else calls, your phone doesn’t ring. Most calls are from people you don’t know - a scam, a robocall, or a political call. For these callers, imp silently takes a message, and then delivers that message to you on your smartphone. If it is a known bad guy imp just hangs up.
