What is the term used by wireless carriers to route calls and identify the originating cell site?

The term used by wireless carriers to route calls and identify the originating cell site is known as P-ANI, which stands for Pseudo Automatic Number Identification. P-ANI is crucial in emergency communications, allowing telecommunication systems to correctly route calls to the appropriate public safety answering point (PSAP) based on the location of the caller. This system provides essential information that facilitates a swift response from emergency services, ensuring they reach the caller’s location promptly.

While VoIP, TTY, and ASL serve important functions in telecommunications, they do not specifically relate to the routing of calls via cell site identification. VoIP primarily refers to the method of delivering voice communications over the internet, TTY refers to telecommunications relay services for the deaf and hard of hearing, and ASL is a sign language used by the deaf community. Therefore, P-ANI is the relevant term in this context as it specifically pertains to routing and location identification in wireless communications.
