WHAT IS IT?
HoW DOES IT WORK?
The best way to understand how our Exchange in a Box works and exactly what it does is to watch our two short Youtube Videos (See Below)
This “Plug and Play” solution is designed to make telephone calls between two standard UK hard-wired telephones. Ideal for use as an internal house intercom system or as a method of making telephone calls for Stage and Screen use.
Most people find it is much better to have a real landline phone actually ring on stage as the sound of the telephone ringing is more localised to the source.
All parts are provided (except the standard landline telephones) and no electrical or computer skills are required, it is literally plug and play.
Although this solution was initially developed as a telephone intercom system for “Vintage Telephone Enthusiasts” it is also used extensively for stage/play/theatre/”escape room” use, competing very favourably (both in function and price) with “Tele-Q” and various older telephone ring generator solutions.
It operates from a UK mains powered DC supply (provided) and will ring both new and old vintage telephones (will ring a REN of 3).
The telephones (not provided) just plug into standard “BT style” telephone sockets (provided).
The system includes two telephone wires (one 17 meters and one 3 meters in length). However standard telephone extension cables can also be used to extend the range by up to 100 meters (provided the telephone extension cable is of good quality) if required.
Please note that this is not a wireless solution, rather it uses more reliable standard telephone wires. Also please note that the solution is “plug and play” and as such has no user configurable options. For example, the ring cadence (UK vs US) can not be changed by the user and has to be pre-set in our workshop.
Before you buy we strongly advise you to watch the “Installation Video” below. This is particularly important if you wish to use the “dialling” on stage and intend to dial out from an old vintage telephone.
Please note that because this solution is specifically designed for UK land-line telephones (the UK have a 3 wire, rather than a 2 wire internal wiring telephone system) therefore this solution will not work without adaptation in the US.
Hence this “Exchange in a Box” is currently only available for sale in the UK.

WHY EXCHANGE IN A BOX
We could not find any simple cost effective solutions that would support both old pulse dial telephones and modern push button phones. We love old dial telephones so we developed our own software solution based on industry standard telephony hardware.
RELIABLE SOLUTION
All our vintage intercom telephony solutions are calibrated on dedicated BT/GPO test equipment.
We believe we are currently the only people in the UK offering these devices. Our system is based on “off the shelf” commercial grade telephony/computer hardware.
We develop the software and provide telephony knowledge to make them work for our customers.
