Expansion Modules

[Yealink Support]

Hi BFeller,

What you really want to do is assigning a blf to the buttons on the separate expansion module via auto provision,right.
I have tested phone on 3CX in my side, and using the template like below:

And the Memory key LED is solid green when the monitored user is idle.
But fast flashing red (200ms),when the monitored user receives an incoming call.
When the monitored user is idle, the supervisor presses the BLF key to dial out the phone number. When the monitored user receives an incoming call, the supervisor presses the BLF key to pick up the call directly. When the monitored user is in a call, the supervisor presses the BLF key to interrupt and set up a conference call.

Thx
