Automatic Multiple Number Dialling
When you press an intercom button, you may find out that the called line is busy or
the called party is absent. The intercom is able to identify these situations and solve
them by Automatic Multiple Number Dialling if one of three automatic dialling modes
is enabled. Up to 6 numbers can be stored for each button.
The three automatic modes (see below) recognise the continuous, busy and ringing
tones, In all of these modes, automatic dialling can be disabled or the required count
of cycles can be preset (1 to 9; if none of the stored numbers is answered, the whole
cycle is repeated starting with the first number again) for each button separately.
You can program Automatic Multiple Number Dialling for selected buttons only,
retaining the others in the default mode, the selection of one of three automatic
dialling modes is common.
Automatic Multiple Number Dialling without Confirmation
This mode can be used in common cases to enable the visitor to get through even if
the called line is busy or the called subscriber is absent. Hence, the second memory of
the button may include the secretary's number, the third memory the porter's lodge
number, etc.
This mode recognises the ringing tone and if the tone ends before the predefined
count of rings, the intercom regards this as a successful connection, this solution is not
fully reliable because detection may be hindered by noise, etc. No message is played
back in this mode.
Evaluation of Situations in Audible Automatic Dialling without
Confirmation

Busy tone Hangs up in approximately 2 seconds and dials the next
number.
Call or silence without previous
ringing tone
Waits for the preset timeout (log-in time), then hangs up
and dials the next number.
Continuous tone (at the PBX, e.g.) Hangs up in approximately 2 seconds and dials the next
number.
