A Public Safety Answering Point (PSAP), a contact center run by the local government, receives a 911 call. An official known as a 9-1-1 dispatcher who has received specialized training answers the call at the PSAP. The phone company provides data about the caller's physical address (for landlines) or geographic coordinates (for wireless) to the dispatcher's computer. When necessary, this information is utilized to send out police, fire, medical, and other services.
