Perfect for our application. I have Vonage running on our home phone network. However, we bought a 1960's Stromberg Carlson 500 rotary phone and placed it where there was no telephone outlet. InstaJack works great, allowing an old phone to send (pulse dial) and receive calls (with an accompanying vintage ringtone). I installed an Instajack transmitter in the upstairs bedroom where there was an empty phone jack and another piece of Instajack installed downstairs where the phone is. Isn't technology great!
