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 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.
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 "Key Events" on page 93
