When multiple calls are on a PDN extension, the LED pattern that appears on the corresponding SDN
buttons is displayed according to the following priority:
Receiving an incoming call → holding a call → on a call → idle
For example, if a PDN extension receives an incoming call while on a call, the LEDs on the corresponding
SDN extensions will show the incoming call.
However, if an SDN extension is handling a call using the SDN button (e.g., on a call, has a call on hold,
etc.), the status of that call will be displayed on the SDN button, regardless of the call status of the PDN
extension.
