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.
