Taking back a parked conversation:
Using function Parking/switching over on the internal S
0
bus, you can park a call that you
are currently making on an ISDN telephone. You can then take this call with the same ISDN
telephone. This means that you can normally plug in and unplug an ISDN telephone on the
S
0
bus at several connecting boxes in the course of a conversation without losing the call.
The transfer must take place within the specified time of approximately three minutes. Since
you are taking the call with the same ISDN telephone, the PBX ignores an entered code
digit.
For information on how to park or unpark a call on your ISDN telephone (or another piece of
ISDN equipment), refer to the manual of the respective equipment (usually menu querying).
The function is also often referred to as TP or Terminal Portability.
To make a query in the room without your calling partner being able to hear you, you can
mute the conversation for as long as you like on DTMF telephones.
Muting a call:
Follow-me has the same function as permanent call forwarding to internal extensions, which
is also described in this manual. The difference is that you set it up at the respective tele-
phone and not at the telephone from which calls are rerouted. This means that you can go
from office to office, for example and take your calls with you.
