Appendix 5 - Programmable Functions
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.
