Sometimes it can be difficult to recognize a radio caller due to background noise or a weak signal. ANI clearly identifies the caller for the dispatcher.
Stop System Abuse:
Some radio users may key-up over one another or say things over the air that are prohibited. ANI identifies these users to the dispatcher, so that corrective action can be taken.
The use of Emergency ANI enables the dispatcher to accurately and quickly identify a user in distress.
Some taxi and towing services assign calls to the first user to respond. ANI allows the dispatcher to verify who the first responder was to fairly assign the call.
