DTMF char
L8 confirms receipt ("Connection confirmed") and mutes the currently
played announcement. The call goes on for the maximum call time as
configured.
These digits are interpreted as control characters (refer to
, Tone
Subs. 4.2
Dialling Control during Call).
Note
The PSTN connection quality is not so high as to identify the above
mentioned situations reliably in all cases. Moreover, excessive noise in
the lift cabin may decelerate automatic dialling (due to inability to
recognise the busy tone, e.g.). In general, DTMF is the most reliable type
of signalling and so is used for confirmation. Thus, the connection is
established (yet for a shorter time than usual) even in extreme cases, e.
g. when
cannot identify the DTMF.

2. Automatic Redialling of Multiple Numbers without
Confirmation (GSM/UMTS/VoIP Only)
This mode is useful where no trained personnel for automatic dialling with
confirmation are available. The called party does not have to press any button. The
two modes share a set of numbers and count of cycles, respond identically to the busy
tone, etc.
The only difference is that the confirmation-less mode detects the ringing tone and
recognises that the called party is off-hook (i.e. answers the call) when the ringing
tone terminates before the timeout end.
