●
The “Courtesy Service” function used to be for directly determining
whether a user was currently busy or not and the corresponding
announcement played. The
Announcer at Incoming call is always played
when it is configured with the firmware version (7.0 release). Then
Announcer at busy is played if this announcement is configured.
Note: Please note the explanations in chapter Update Notes starting
on page 25 as well.
Busy Keys
You can configure busy keys on a system telephone or on a SIP system phone.
Busy keys show the busy status of another subscriber (by means of an LED
and depending on the configuration also with an acoustic signal) and can also
be used for the one-touch dialling and pickup functions. You can set up busy
keys on the system phone (authorisation:
Program busy keys ) as well as in
the Configurator on page Telephony: Devices: System phones . When
configuring a key on the system phone, in the Type list, select the feature
entry and the key type Busy lamp Phone No. (busy indication of one single
internal number) or Busy lamp Device (busy indication for the line keys of a
device). For a SIP system phone, select BLF from the Type list.
In contrast to previous versions of the system software the type of busy key
has been changed from
Trunk key to Function key in release 7. This means
that busy keys can be programmed on any number of devices in release 7. A
previously existing configuration of busy keys is automatically converted
when the system software is updated.
Tip: A busy key for virtual call numbers with destination call number
is not supported (see
Virtual Call Numbers starting on
page 245). It is possible, however, to configure a busy key for a
virtual call number without destination call number. When the
virtual call number is called, the call is signalled by the busy key.
The call can be retrieved with the busy key.
Busy keys on the system network
Busy keys on the Forum 5004/5008/5012 communications network are
realised as a subscriber model. A busy key requests busy information to do so.
The destination of a busy key keeps a dynamic list of terminals which have to
be reported when there is a status change. This function mode is optimised for
