Remember also that VoIP systems can go down if the power is out or your broadband connection fails, so you may want to get a generator to supply power to your VoIP phone line. Many VoIP systems are completely portable, working from any broadband connection — in essence, the “phone number” is an IP address. He stayed on the line for 20 minutes, listening intently to nothing but some background noise and, finally, a smoke alarm, until the woman regained consciousness for long enough to provide some partial address information. At the PSAP, mapping equipment (typically the CAD equipment discussed in the previous system) converts those coordinates to a street address that the call-taker can understand and provide to the dispatched emergency personnel. Once the network has the latitude and longitude coordinates of the phone, it can send them with your voice call to the network switching station. The network-based solution is different from the handset method only in how the phone generate its latitude and longitude coordinates. Using trilateration (the same method used in GPS technology), the network can then pinpoint the location of the cell phone to an accuracy of 100 to 300 meters. For proprietors of websites, internet influencers, and writers, it is a popular method of earning cash online.
Another example is Givling, a website where people can play trivia games to win cash prizes. Some free online games not blocked by the military include Strikeforce Heroes and City Siege.

One of the most prestigious banking organizations in India, RBI offers one of the most dynamic and challenging career opportunities in the banking sector. If necessary, call-takers can bring in a translator via a service like the AT&T Language line, which offers translators for about 140 languages. Stay on the line, speak clearly and follow the operator’s instructions. What happens next varies with different systems, but one typical approach is pretty much a mobile mirror of the landline Enhanced 9-1-1 process. They found the right apartment and rescued a 21-year-old, unconscious pregnant woman who likely would have died from smoke inhalation if she’d remained undiscovered for much longer. The call-taker dispatched emergency personnel to the apartment building the woman indicated, and they knocked on doors until they heard their own knocking through the radio link to the PSAP.
In the far future, it could allow for the transfer of multimedia files, like a caller’s cell-phone video clip of the emergency she’s reporting, directly to the call-taker’s computer screen. Some counties are starting to transfer 9-1-1 information via secure Intranet instead of relying only on phone lines. Some mistakes that callers make include calling 9-1-1 and then leaving the phone or just hanging up, assuming the operator has all the necessary information when in fact he or she may have no information at all. If possible, be aware of your surroundings so you can tell the operator exactly what’s happening and where it’s happening. Dial 9-1-1 and wait for operator to pick up. The phone you carry around has a full GPS receiver built-in, and when you dial 9-1-1 on the phone, the GPS receiver locates itself using satellites orbiting overhead. When you dial 9-1-1 on your phone, the phone sends out radio signals to at least three of these towers, and the receiver in each tower times how long it takes for each signal to reach its receiver. It taps into radio signals emitted by at least three satellites and times how long it takes the signals to reach the receiver.
In most home VoIP setups, voice signals start in the PSTN, switch to the Internet for the majority of their journey, and then get back on the phone lines. If the type of internet is DSL internet, then a visit will likley be required. Using trilateration, the receiver can then determine its location (see How GPS Receivers Work to learn all about trilateration). The caller was using a cell phone, and this PSAP had not yet implemented Phase II, so the call-taker had nothing but a very vague general location and a call-back number. The original patent for Super Glue (cyanoacrylate) was actually filed in 1942; however, nothing actually came out of this endeavor. Fiber optic cables came into the market, and cable companies started using them for all the trunk lines in the system. Some estimates have about 15 million people in the United States using VoIP by 2008. When VoIP systems first gained popularity, there were some problems when it came to accessing 9-1-1 emergency services. We’ll look at these next.Another technology that can cause problems in 9-1-1 emergencies is VoIP, or voice-over-Internet protocol. Is there anything I can do to help?
