How 9-1-1 Works

9-1-1 Calls Placed From Wireline
When a 9-1-1 call is placed from the wireline telephone, such as your home or business, two things happen simultaneously that assist call-taking personnel in gathering incident location information.

First, the call is selectively routed via the 9-1-1 network to the correct 9-1-1 Public Safety Answering Point (PSAP). Selective routing is sending your call to the most appropriate answering point based on your address.

At the same time your call is being routed to the 9-1-1 database which recalls the address associated with your telephone number. Both elements are delivered at the same time to the operator thus decreasing the amount of time needed to assess your location. This is especially helpful when the caller is unable to give their location.

The 9-1-1 call taker will then assess the nature of your emergency and enter your call into a computer aided dispatch system. Based on the incident type, police, fire, and/or emergency medical services will then be dispatched. If your call is medical in nature, you may then be transferred to emergency medical services personnel for additional assessment and pre-arrival instructions.
