Telephone Exchange Intercom for Rotary Phones, Room-to-Room Calling

New Product for rotary phone lovers! Possibly the only Phone System available to Call Room-to-Room! Not just for looks anymore: I designed this product for my wife’s rotary phone collection. We had 3 phones in the house, and we don’t use a home phone line. She bought fancy phones on Ebay, and wanted to use them in the house- calling me from her office or bedroom, to my workshop. We tested this and have finally put in this system to call between 5 phones in our house. She calls me for lunch on a rotary phone! It has been a lot of fun to use. Never worry about a bill! Features: Call from Phone 1 (bedroom, office, etc) to phone 2 ( kitchen, hallway, etc) Box operates up to 5 phones Does not require a telephone service DEMO VIDEO AT https://youtu.be/PAKqknLOgzcNew Feature!
