Automatic Dialling of Multiple Numbers without Confirmation
This mode is useful where no trained personnel are available because the called person
does not have to press any button. The two modes share a set of numbers, count of
cycles, response to the busy tone, e.g., and so on. The difference is that the
no-confirmation mode recognises the ringing tone and if the tone ends before the
preset count of rings is exhausted, it means that the called user is off-hook and this is
considered a successful connection.
Caution
The PSTN connection quality does not allow for recognition of all the
above listed situations. In addition, excessive noise in the lift cabin can
adversely affect (decelerate) automatic dialling making it impossible to
recognise the busy tone, for example. In general, DTMF is the most
reliable confirmation signalling method as DTMF connection is always
established (yet for a shorter time) even if
fails to recognise 2N Lift1

DTMF.
Warning
Check the no-confirmation mode before use because ringing tones may be
different in different countries/providers and may not be recognised
correctly.
Note
In this mode, does not repeat the "Wait please" announcement 2N Lift1

(or any other user message) after dialling because it would be impossible
to recognise ringing reliably. The message is played once and shortly after
the called user picks up the line.
