Hold
External calls can be put on hold in your telephone system. The hold function will
be initiated and terminated by pressing the
key. Your conversational partner will
hear music while he/she is on hold.
In case you hang up while there still is a call on hold up to 45 seconds a call back
will be carried out. In case the call is not being picked up again the telephone
system will disconnect the caller on hold after those 45 seconds.
Conference (internal)
To an existing internal telephone connection additional parties can be added to
have an internal conference. The door intercom system, however, can not take
part in such a conference. The initiator of the call can add one additional
subscriber. Due to the private nature of the conference no external subscriber can
join it.
Example: Two internal subscriber 22 and 23 have a call and want to consult a third
subscriber 25 in conference.
Dial internal number
.
Telephone 25 is being called (max. 20
seconds). Subscribers22 and 23 hear the
calling signal. In case telephone 25 is busy
you will hear the busy signal for 3 seconds.
Telephone 25: Pick up handset.
The connection between all conference
participants will be set up.
Hang up.
To leave the conference just hang up. The
subscribers left can continue their call.
Switch off tone dialling temporary
With internal connections tone dialling detection is active. The detection by the
telephone system of DTMF (dual tone multiple frequency) signals generated by the
telephones can temporarily be deactivated. This can make sense and is necessary
if e.g. you would like to remote access an answering machine or you wish to send
DTMF signals as data. Tone dialling detection can be switched off by pressing the
key during an internal call.
