Link
: Linked functions are executed consecutively after the relevant key is
pressed. This makes it possible to combine complex system telephone
settings on a
single
feature key. You can programme more functions in a
link than you can on a single feature key. A concrete setting for a function
can be saved in a link (e.g on/off for “call protection”). This means that a
function in a link has an exactly defined switching function in comparison
with the functioning of a single feature key.
Special Feature Keys
Busy Keys
Busy keys are feature keys as well. A busy key shows you the busy state of
another internal subscriber. There are two kinds of busy keys:
●
Busy Key “Call Number”
: This busy key shows the busy status of a single
internal call number. This can be an internal call number of your own
communications system or a call number of a system which can be
reached via the telecommunications system network.
●
Busy Key “Device”
: This busy key monitors all trunk keys configured on a
terminal. If one of these trunk keys is busy, the busy key signals that the
terminal is busy.
Notes
●
You can configure up to 50 busy keys per SIP system telephone (includes
telephone and connected expansion modules).
●
Busy keys are not supported on the Forum IPhone 5010 SIP system tele-
phone.
●
Users cannot prevent authorised users from monitoring their call numbers
via busy keys on their terminals.
