Set up and use of Yealink T19, T2- and T4 -series phones on the Cloud PBX server
8
User button LED modes
The User buttons are implemented as SIP BLF keys. Yealink LED mode 1 is the only mode
supported by the cloud PBX.
When a key is assigned to monitor an extension, the behaviour of the LEDs is as follows:
LED unlit: extension is idle
LED flashing red: extension is ringing
LED solid red: extension is busy.
Note: If the Yealink phone is programmed to use a LED mode other than LED Mode 1, this
will be over-written by the Cloud PBX and the phone will revert to LED mode 1 when it is
reconnected to the server or powered down.
Feature example: Using Listen, Whisper and Intrude
Assign keys to the Listen and Intrude functions, by selecting from the Function Keys drop-down
menu, under the Function Keys tab, at the User Portal.
Whisper uses the Listen button. Pressing it toggles between listen and whisper and the led color
changes. Green is for Listen mode, red for whisper.
Dialing 7 will toggle between the listen and whisper modes.
Dialing 9 will go from Listen or Whisper mode into Intrude mode.
There’s a separate Intrude key.
Pressing Intrude, when the phone is idle, displays a list of the active calls that can be intruded on. To
intrude, select the call from the list.
Pressing the Intrude key, while in listen/whisper mode has no effect.
