What is a PANI in the context of wireless 911 calls?

  1. A telephone number used for billing

  2. A routing system for SMS messages

  3. An address for the recipient

  4. A telephone number used to support the routing of wireless 911 calls

The correct answer is: A telephone number used to support the routing of wireless 911 calls

In the context of wireless 911 calls, a PANI, or "Pseudo ANI," refers to a telephone number used to assist in the routing of emergency calls effectively. When a wireless caller dials 911, the call may not always provide traditional Automatic Number Identification (ANI) due to the nature of cellular technology. In such cases, the PANI is utilized to help telecommunications devices, such as those at a Public Safety Answering Point (PSAP), determine the origin of the call and connect it to the appropriate emergency services. This is crucial for ensuring that responders can quickly and accurately assess the location and details of an emergency, which is vital for effective response. The other options in this question do not accurately represent the function of a PANI within the 911 emergency response infrastructure.
