This means that when all line/call appearances are in use, 1 call is connected while the rest are
on hold. No further outgoing or incoming calls can be made until one of the line/call
appearances becomes available.
In active states, such as ringing, conference, connected, etc., all softkeys disappear except
softkeys that have been set up as line/call appearances, and any context dependent softkeys
required for the active state, such as the Drop softkey in the connected state. Typically, context
dependent softkeys appear in the top left position and all line/call appearance softkeys appear in
the remaining positions.
You use the Aastra Web UI to set a softkey as a line.
