OK, got a question on 911. Looking into setting up a couple asterisk servers at a country club, with VOIP phones in each of 100 short-term residential rental units. Approx 100 extensions, approx 24 outside lines. Since everything is geographically at one location, reaching 911 correctly shouldn't present a problem. However, the club wishes to ensure that 911 authorities are able to identify the precise rental unit placing the call. How can we achieve this, short of 'reciting' the unit number aloud at the beginning of the placed call? Thanks for any advice/tips. j
With hotel systems When some places a 911 call it is printed on the printer in the Front Desk, Hwen help arrives they usually go to the Frount Dsek anyway. I would set up a System() that would not only printout he romm number on the Front Desk Printer but also drop a call file in to trigger a call to the Front Desk with a prerecorded message of wht extention just called 911. That way the Hotel can send someone to the room to act as first response and the Frount Desk can direct the 911 team to the correct location.> -----Original Message----- > From: asterisk-users-bounces@lists.digium.com > [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of > Joel Newkirk > Sent: Friday, September 30, 2005 10:20 AM > To: asterisk-users@lists.digium.com > Subject: [Asterisk-Users] 911 Q > > OK, got a question on 911. > > Looking into setting up a couple asterisk servers at a > country club, with VOIP phones in each of 100 short-term > residential rental units. > Approx 100 extensions, approx 24 outside lines. > > Since everything is geographically at one location, reaching > 911 correctly shouldn't present a problem.

You might have to work with your phone company/LEC on this, but I think it would be the most transparent solution. Ray
I installed a "Marquee" sign (aka reader board), which was sent emergency information via an RS-232 serial port. It was pretty nifty, as it was during to 'everywhere must have caller ID' phase in the 90s. Most signs are cheap, and can just be placed in the clubhouse window.

When you dial 911, your call is routed to the appropriate PSAP (Public Safety Answering Point) based on your ANI (Automatic Number Identification) or ELIN (Emergency Line Identification Number -- usually just another term for ANI). As your call arrives, the PSAP does a query of their ALI (Automatic Location Information) database to get your location information. Please note that the PSAP does NOT use Caller ID for this purpose. End users are not able to block their ANI (under normal circumstances), even though they may block their Caller ID. Either the ILEC or a company like Intrado will maintain the ALI database in your area. If you are getting your PRI and DIDs from your local ILEC, they would be responsible for getting the correct information entered into the ALI database. Typically, the information entered is only the physical address where the primary service is installed. In most circumstances, this information is enough to get police/fire/EMS to you in an emergency. However, I suspect the entire country club shares a single street address. If so, when someone dials 911, the PSAP will get only the main address of the country club. In this and similar situations, such as calling from within a multi-floor office building, a campus environment, etc., the main street address is simply not enough information to get emergency responders to you in a timely manner. Consider this not-so-unusual hypothetical scenario. A guest of the Pennsauken Country Club is having a heart attack in his bungalow. He dials 911. The dispatcher's screen at the PSAP shows the main information for the club "(856) 662-4961 - 3800 Haddonfield Rd - Pennsauken Country Club - Pennsauken, NJ". The guest explains that he is experiencing severe chest pain, then either passes out before he can tell the dispatcher his exact location at the country club, or is confused or unaware of his exact location. The dispatcher would roll fire, EMS, and/or police to the main address. However, when they arrive, the emergency responders would have to knock on all 100+ doors to even attempt to determine who was having the emergency. Now you probably have a dead guest. Not good for business. First off, you should be using a PRI to connect your Asterisk server to the PSTN. You should also have a block of DIDs, with each guest room assigned its own, unique DID. This way you can differentiate among the individual rooms when people are making outbound calls, and guests may receive incoming calls in their room without going through an operator. Asterisk is capable of setting ANI in addition to Caller ID, on a per-call basis. This would ensure that the correct data is sent to the phone company when someone dials 911. As to getting the data to the PSAP to indicate where within the country club each DID is assigned, you have a couple of solutions. You can implement PS/ALI (Private Switch/Automatic Location Identification), or you can work with your telecom provider to have them enter the extended data into the ALI database for each DID individually. PS/ALI is the "best" solution, from a technical standpoint -- but it is usually quite expensive. PS/ALI allows you to provide the E-911 system with current, specific tenant location information to expedite emergency response times to the site of the emergency -- not just to the building or general site location. So when your guest having a heard attack in room 119 dials 911, the PSAP gets something more along the line of "(856) 324-4119 - 3800 Haddonfield Rd - Building 5 Room 119 - Pennsauken Country Club - Pennsauken, NJ". PS/ALI is geared toward larger telecom users such as colleges, office buildings, large office campuses, etc., with a somewhat mobile population. It is utilized best when most of your extensions or DIDs are assigned to a person, as opposed to a location. This way, when the person moves from one office to another, your staff can push the change to the ALI database within minutes of the move, rather than phoning in a service order to the LEC, and waiting days for the change to be pushed to ALI. In your situation, I am assuming an extension or DID would most likely stay at a fixed location for quite some time (e.g. extension 4119 is always going to be guest room 119). So PS/ALI may be overkill in your situation. In that case, I would go the second route mentioned above. Work with your telecom provider to get them to maintain the extended data in the ALI database for each of your DIDs. There may be a fee for them to do so, but I am certain it is much less expense than the charges for PS/ALI. Keep in mind that any changes to the location data would require you to place a service order. Let me know if you have any questions, or if I was unclear on an item. Sincerely, Trevor Hammonds

Richard, Can you give some more details on COMPARE_TONE_AND_SILENCE please? I tried the busypattern setting, but it did not help.

With busypattern= the tone and silence periods must be within 10% (IIRC) of the time you specify. Steve
