What is the main function of a P-ANI?

The main function of a P-ANI (Public Automatic Number Identification) is to identify and route calls coming from a cell site. This system is crucial in emergency situations, as it allows for the identification of the originating location of calls to emergency services, ensuring that first responders can quickly and accurately reach the place where assistance is needed. The P-ANI provides vital information that helps in the correct routing of calls, which is essential for effective emergency response.

Other options, while relevant to telecommunications, do not specifically pertain to the predominant function of a P-ANI. For example, calling statistics are more related to usage data rather than real-time call routing, and connecting to landline numbers focuses on voice communication pathways rather than identification processes. Enhancing VoIP quality addresses a different aspect of voice transmission technology, which is not the primary purpose of a P-ANI.
