What is a lift auto dialler?

In the unfortunate event of persons becoming trapped, gone are the days where a lift alarm alone is sufficient, any lift in a low traffic environment or building which is not permanently manned must have an auto dialler installed, when the end users presses the alarm button this connects to the lift service provider via the lift auto dialler; this allows the trapped passenger to communicate with the lift company. Two types of system are available; the first being through a phone line that can be provided by BT but will attract line rental, the second being a GSM with a pay as you go sim system available with most network providers such as O2.
