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").
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 field 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 first 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 field 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".
Line Default setting for all freely programmable function keys. Incoming calls will go to
the first free "line" key, and outgoing calls will use the first free line key.
Line keys can be used to make outgoing calls with the identity selected from a
particular key's "Context" menu and to have incoming calls for that identity going to
that particular function key. If the key is busy, the incoming call will go to the first free
line key.
