What is the function of the ANI feature of an enhanced 911 system?

• A. Provide the caller's identity
• B. Lock the caller's phone open
• C. Show the caller's phone number
• D. Show the caller's location

Answer: (C)

Automatic Number Identification (ANI) transmits the caller’s telephone number to the public safety answering point during an enhanced 911 call. This allows the dispatcher to identify the originating line, call back if the connection is lost, and aid in routing and record-keeping. ANI does not provide the caller’s name or personal identity, nor does it lock the phone. Location information is handled separately by location services (ALI, etc.), which provide the caller’s address rather than the number. So showing the caller’s phone number is the function illustrated by ANI.
