Q. When I call 911, how does the dispatcher know where I live?
The 911 system is connected to computers at the telephone company so the address and telephone number of the caller is printed out on a screen as soon as the dispatcher answers the all. In the event the caller hangs up prior to speaking with the dispatcher, the caller's information is still locked into the 911 system and is retrievable by the dispatcher. More than once, a 911 caller with a medical problem, has been unable to speak into the phone. Using the stored information, the dispatchers were still able to send aid using this feature.
