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