Remarks
Call preemption occurs when a precedence call is sent to a preemptable endpoint
that is busy with a call of lower precedence and has no idle appearances.
This causes the lower precedence call to be preempted, regardless of whether
the lower precedence call and the new higher precedence call are of the same media type.
When preemption occurs, the active busy user receive a continuous preemption tone until user
acknowledges the preemption by invoking complete preemption method and the other party receives
a preemption tone for a minimum of 3 seconds.
After acknowledging the preemption, the extension to which the precedence call is directed will
be provided with precedence ringing and the calling party will receive an audible ring - back
precedence tone.
Application must start playing preemption tone upon receipt of event Preempted
and stop preemption tone before calling completeCallPreemption when user acknowledges the preemption.
However when other end receives preemption application must stop tone after 3 seconds and
Preempted is NOT needed since there is no precedence call is directed at this
end, other end is free and ready to receive any other new call while tone is being played.
