Making Calls
you have selected is not dialled until you lift the handset or press
the hands-free key
. It is useful to activate the “Block dial-
ling” feature when using a headset (see the section entitled
Menu-
Card “Phone Settings”
starting on page 92).
If block dialling is switched off, the telephone switches to hands-
free mode or open-listening mode as soon as you enter a call
number and dial it.
Block Dialling and Headset Operation
It is useful to activate the “block dialling” feature when using a
headset. Once block dialling has been activated and the headset
switched on, the phone immediately switches over to headset
operation and the call number is dialled when you enter a number
on the phone.
Dialling a Different User or a Different Terminal
You can also use your system phone for dialout with a headset. To
do so, save a destination call number on your system phone (via
the MenuCard
Connections
, the menu entry
2ƒDial: 0ƒRemote
dialling
, please refer to page 99 also). The saved call number
will be dialled automatically when you press the headset key
within 30 seconds. After 30 seconds, the dialout will be deacti-
vated automatically.
This feature can be used on all devices for which the system
administrator has configured a device ID. This means that you can
also save a dialout for another user who, e. g. also has a system
telephone.
DTMF Postdial/VF Signalling
Depending on the system’s configuration, your telephone is auto-
matically set to VF (voice frequency) signalling in the connection
state. You can use this, for example, to query an answering
machine or a voice mailbox. Consult your system administrator if
you have questions concerning this function.
With the Forum IPhone 520 and Forum IPhone 530 telephones no
postdialling via DTMF is supported for ISDN or SIP lines.
