The Interquartz Programmable Telephone is a pre-programmable telephone for restricted dialling applications that can be set up with either 1 or 10 buttons showing. Because it has no keypad, it is unattractive to thieves, and calls cannot be made to unauthorised numbers. Each button can be programmed with either an internal extension number or an external telephone number. The telephone can be programmed by purchasing an Interquartz Keypad Emulator. Alternatively, ask for details of our in-house programming service when ordering.
