Terminal indicators
The IP Phone terminal uses light-emitting diodes (LEDs) of different colors
to indicate the current state of the terminal. The following table describes
each color and its associated state.
A steady indicator means that the extension or feature beside it is active.
A flashing indicator means the line is on hold or the feature is in the
process of being programmed.
