Abstract
A system receives an emergency call, a local exchange carrier (LEC) charge number, and Calling Party Number (CPN) from a user device, and overrides the LEC charge number with the CPN for Automatic Number Identification (ANI) determination purposes. The system also determines the ANI of the user device based on the CPN, receives an address associated with the user device based on the ANI, and provides the emergency call and the address to a Public Safety Answering Point (PSAP).
