PSAP, Public Safety Answering Point.

PSAP (Public Safety Answering Point) or E911 is the # that you would get if you were to call 0, then have your operator connect you to your poliece department or fire department.  These numbers are a regular 10 digit telephone number, such as: 650.***.6131 (Atherton Poliece in San Mateo County, CA), or 650.***.2404 (Atherton Fire in San Mateo County, CA). 

These numbers are made so that the operator can just transfer your call (or we think), since most operators will only connect you if you have an emergency to get ahold of the poliece or fire dept.  

We at UPIN (United Phreaks Intelegance Network ( have some fun with these numbers at times, such as calling the PSAP for Montana many times on occasion, calling in false calls, then conning the officer into saying, "UPIN 0WNS 911".  It took some work, but we got it through..  

The following is an excert from Massachusetts State Police ('s website:

  In 1994, the Town of Hatfield joined the Massachusetts State Police Enhanced 911 (E911) Public   Safety Answering Point (PSAP). This center is located inside the Northampton State Police        barracks on King Street in Northampton and is staffed 24 hours a day. All calls for police,      fire, or ambulance services in Hatfield are handled by this PSAP. This PSAP is a regional        dispatch center that receives police, fire and ambulance requests for fourteen Western           Massachusetts towns in Hampshire and Hampden counties. It also answers most of the cellular      emergency calls for all of Western Massachusetts. 

  The "E" in E911 stands for "enhanced." Enhanced 9-1-1 service was adopted in Massachusetts in    1990 and is a great assistant to the emergency dispatch operators. If you dial 9-1-1 from a      land-based telephone in the Town of Hatfield (not cellular telephones), your call will be        routed to the Northampton PSAP. At the same time the dispatcher answers your call, a small       video screen in front of the dispatcher displays your name, your address, your telephone         number, and any special disability indicators you may have. This information is called the       ANI/ALI (Automated Number Index, Automated Locator Index) and in the event you are unable to     speak, the dispatch center has this minimal information about from where you are calling and     can send help to you right away. Even if you have Caller ID Blocking or Anonymous Call           Rejection activated on your phone, the ANI/ALI information will still go to the PSAP.

  In addition to handling 9-1-1 emergency calls, this PSAP is responsible for facilitating radio   communications between the Massachusetts State Police cruisers from the Northampton and          Springfield barracks. The dispatchers provide officers with critical information from the        Massachusetts Registry of Motor Vehicles, the Criminal History Systems Board, the National       Crime Information Center, the Federal Bureau of Investigation, and any other police department   in the United States and its territories via the CJIS terminal computer (Criminal Justice        Information System). This system can be queried to check for outstanding warrants, stolen        vehicles, and missing persons. Dispatchers also have the ability to communicate with other       police departments over the radio via the W.M.L.E.C. system (Western Massachusetts Law           Enforcement Channel) in the event of an inter-city emergency or mutual aid situation. Civilian   dispatchers work in shifts of two or three 24 hours a day.

If your thinking about pranking them, another excert is:

  Another benefit of Enhanced 911 service is that the ANI/ALI information comes into the dispatch   center as soon as you finish dialing the last "1" in 9-1-1. Even if you hang up the phone        before the dispatcher answers on the other end, your ANI/ALI information has already been        received at the PSAP. Likewise, if your phone is disabled before the call is answered (for       example, your phone is ripped out of the wall during a domestic dispute) the ANI/ALI             information will still be received at the dispatch center.

  While this information is invaluable in the event of a real emergency, it can lead to the        unnecessary activation of police, fire and ambulance personnel for accidental or false 9-1-1     calls. It is very important that if you accidentally dial 9-1-1 you remain on the line and tell   the dispatcher that the phone call was accidental. Answer all the questions the dispatcher asks   and do not hang up until you are told to do so by the dispatcher. The dispatcher will take the   time to confirm that your ANI/ALI information is correct so that in the event of a real          emergency help can be sent to the right location.

And last but not least, some crittearia information:

  In the event of placing a 9-1-1 call and you are unable to speak to the dispatcher, press the    following number corresponding to your emergency:

  Press 1 if you need the POLICE 
  Press 2 if you need the FIRE DEPARTMENT 
  Press 3 if you need an AMBULANCE 
  All dispatch terminals are also equipped to communicate with teletypewriters.

  It is important to remember that most 9-1-1 calls from a cellular telephone are answered by      this Northampton PSAP. Some calls generate ANI information and some don't. Because a cellular    telephone is mobile, it is impossible for the 9-1-1 operator to know exactly from where you are   calling. For example, a cellular telephone user in Pittsfield, Massachusetts dialing 9-1-1 will   reach the Northampton PSAP. It is extremely important the you always say what city and state     your emergency is in when dialing 9-1-1 from a cellular telephone. Stay on the line and answer   all the dispatcher's questions and do not hang up until you are told to do so.

Every state has some PSAP's, you can find listings of some of them online, we found like 20 lists through yahoo, google, msn, etx.  So it would be fairly easy to find around 50-100 for your state, hell, for one section of cali, we found over 200..  and for Oregon, we have a list for about 120, and WA we have a list for around 300 (3 lists combined).

Well kiddies, thats all for Gizmo's little scheme on PSAP (E911), use this information as you must, if you need any help, feel free to stop by at and ask, or reach me on DALNET under the nick Gizzy in #upin.
