911 is a massive network that helps cover all the emergencies. Naturally, 911 cannot simply hold all departments. Therefore, 911 is linked to multiple department to which they can transfer your call easily. Some center only cater to fire emergencies or police emergencies and respond to them.
Others have dispatchers that instantly alert the respective department with the details of the caller’s location and the kind of emergency. The entire process only takes a few minutes that help deliver instant help to you no matter where you are. Some other centers help filter your calls even before an operator picks up the call by transferring you to a center nearest you.
In most of the cases, the calls to 911 get redirected to the communication center that is the closest to you. However, there are some 911 communication centers that can only take care of fire or police emergencies. For medical emergencies, your call may be routed to a different communication center.
Once the call comes to a communication center, the computer at the dispatchers end is used to transmit a digital signal as a request to retrieve the phone’s location. This exchange of data can take a few seconds to a couple of minutes. This is how 911 calls get directed.
