A user group is busy if all its members are busy and neither the Operator Console
element nor the General call element is activated.
If a user group is busy, an incoming call is routed to user group 16.
Call destination: Busy KT Line
If an incoming call is routed to a busy KT line, the call will be rejected and the caller
obtains the busy tone.

If a subscriber has stored a message, an incoming call will be routed to the prede-
termined call diversion destination.
If a predetermined call diversion destination has not been defined, the subscriber
will be called nonetheless.
