Call Preemption
Call Preemption allows a radio to stop any in-progress
voice transmission and initiate a priority transmission.
With the Call Preemption feature, the system interrupts
and preempts ongoing calls in instances where trunked
channels are unavailable.
Higher priority calls such as an Emergency Call or an
All Call preempt the transmitting radio to accommodate
the higher priority call. If no other Radio Frequency (RF)
channels are available, an Emergency Call preempts an All
Call as well.
5.6.8
Voice Interrupt
Voice Interrupt allows the user to shut down an in-progress
voice transmission.
This feature uses reverse channel signaling to stop the
in-progress voice transmission of a radio, if the interrupting
radio is configured to Voice Interrupt, and the transmitting
radio is configured to be Voice Call Interruptible. The
interrupting radio is then allowed to make a voice
transmission to the participant in the stopped call.
The Voice Interrupt feature significantly improves the
probability of successfully delivering a new transmission to
the intended parties when a call is in progress.
Voice Interrupt is accessible to the user only if this feature
has been set up in the radio. Check with your dealer or
system administrator for more information.
