Conference This function key can be used for PBX-based conferences and for local
Server conferences on the phone itself.

DTMF This funcion allows the specification of arbitrary key sequences (allowed digits:
"0-9", "*", "#", "A-D" and flash: "!") which will be sent via DTMF when this key is
pressed during an active call.
Extension This function key allows showing the status (idle, ringing, held call, busy) of
another extension on the key's LED. By pressing the key, it may also be possible
to pick up calls ringing on the extension, to dial the extension when the phone
is idle, and to transfer an incoming call ringing on your own extension. These
functionalities depend on your PBX; for more information, please check snom's
interoperability page and the PBX manual. With Asterisk, generally use BLF
rather than this function.
Forward to All incoming calls will be forwarded to the number (extension or external phone
number) specified under "Number". The key is used to turn forwarding of all
calls on and off; the red LED lights up when the function is turned on.
Intercom Pressing a function key mapped with "Intercom" will establish a two-way
connection to the extension specified in the "Number" text field; that extension
must have enabled intercom reception on its web interface (Advanced Settings >
Behavior tab > Phone Behavior > Intercom Policy "only in idle" or "always").
"Intercom Policy" settings on the phone being called via intercom:
Always: The intercom call will connect to the called phone automatically; if the
called phone is in a call, that call will be placed on hold.
Only in idle: The intercom call will connect to the called phone automatically
if the called phone is idle. If it is in a call, the incoming intercom call will be
announced as call waiting.
Off: Pressing the intercom key will call the extension specified in the "Number"
text field where it will be treated like any other incoming call, i.e., ring, be
forwarded, etc.
PBX-based conferences. When a conference room or conference account
has been created on the server for an individual identity, you can dedicate
a function key to calling and monitoring the conference room. Select the
identity and the "Conference server" function from the respective drop-down
menus and enter the SIP URI of the conference room in the "Number" text
field. For information on how to use this key with your particular PBX, please
check the PBX manual.
Phone-based conferences. If there is no SIP URI in the text field, pressing
the function key will initiate a phone-based conference with all held calls and
any active call.
