DTMF This funcion allows the specication of arbitrary key sequences (allowed digits: "0-9", "*",
"#", "A-D" and ash: "!") 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)
specied under "Number". The key is used to turn forwarding of all calls on and o; 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 specied in the "Number" text eld; 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.
O: Pressing the intercom key will call the extension specied in the "Number" text eld
where it will be treated like any other incoming call, i.e., ring, be forwarded, etc.
IVR This function key can be used for regular calls to an extension that is reached via an
IVR or auto attendant and a number of voice prompts where the caller has to make a
selection by pressing a key after or during the prompt. If you know which keys need to
be pressed in which order in order to reach the desired extension, the entire process can
be automated and considerably speeded up.
The syntax for the "Number" text eld entry is <phone_number>;dtmf=<n>,<n>, etc. The
angle brackets <>including their content are placeholders for the variables that you
must replace by the actual characters. The comma represents a pause of one second,
and n represents any number key on the alphanumeric keypad.
Example: The number to dial is (917) 555-3814. When the connection has been
established, the caller will hear three prompts. After the rst prompt, he must press key
1; after the second prompt, he must press 3; and after the third prompt he must press
1 to reach the desired extension. The entry in the "Number" text eld must look like this:
9175553814;dtmf=1,3,1.
Usage: When the phone is in idle mode, press the key to dial the number. As soon as
the connection has been established, the phone will automatically send the DTMF tones
associated with the alphanumeric keys 1, 3, and 1 with a one-second pause between
them.
(If the function type "IVR" doesn't work on individual phones, try "Speed dial" with the
above description.)
Key Event When this key type is selected, a drop-down menu opens under "Number". For the
available selections, see the following section "Key Events".
