VoIP 911 Emergency Service: Problems and Fixes

13.7BillionYears writes "Slate explores the technical hurdles VoIP faces in providing 911 emergency services and points to some technical, legislative and commercial workarounds that just might work. Some are the author's own ideas, some are already in the works. Until this little doozie gets solved, VoIP will have to suffer plenty of FUD of the credible variety and may never spark a real revolution. Of course you can always keep analog POTS (plain old telephone service) around like floppies--just for emergencies--but it'll cost you and tie you down in a number of ways."

  1. Know your location? by cloudmaster · · Score: 4, Insightful

    Like it's real hard to just remember your address and tell them on the phone where you presentaly are located... If you can't speak, well, it's probably too late for you anyway - and if you're in a strange place, odds are you either 1) know where you are or 2) aren't in a location using VOIP. :)

    "Of course you can always keep analog POTS (plain old telephone service) around like floppies--just for emergencies--but it'll cost you and tie you down in a number of ways." ..I'm not 100% sure if landlines work this way, I would assume so, but I know for cell phones, even a non-activated cell phone can still dial 911. So go ahead and switch to VOIP, even if you don't have a cell phone, keep an old one charged up.. if theres an emergency, you can call 911 on it.

    Isn't it funny how everyone is trying to keep VoIP unregulated, but then can't get 911 services. It's a compromise either way.

    Time Warner Cable in Austin has VOIP with enhanced 911 service.

    Q: Can I call 911?
    A: Yes, absolutely. Safety is important, and enhanced 911 service is provided. Note that Digital Phone does not include back-up power and in the event of a power outage, the ability to call 911 will not be available until the power is restored.

    My Vonage line has 911 service. It takes them a few days from the time you order to process your physical address, locate the local emergency services that are relevant, and tie it all together into their 911 call center, but once it's set up they claim it all works fine.

    Obviously it won't correctly know your location if you pick up your home VoIP box and take it to a hotel or a starbucks access point or something like that - but those sorts of challenges should really be solved by a next generation of 911 technology (which would be as simple as saying that every phone of every type must have a gps receiver, and must send the gps data encoded in some form when dailing 911 (I'm picturing you dial 911 and you hear some high pitched screeches right at first where the call center requests GPS and your phone answers, using analog-modem-like modulation).

  6. Pots..... by Interested+Guy · · Score: 4, Interesting

    I have been playing with this VoIP stuff a lot lately. My wife has worked for our county 911 office for quite some time, so this is a big concern.

    There are some ways around this... My Router (Sipura spa-3000) can route calls out to a POTS line if you dial 911. You just gotta have a pots line.. My provider (Qwest) will sell me a measured service line for 9 bucks per month. Incoming calls are free, outgoing calls cost 2 cents for first minute one cent for additional minutes. (They didn't advertize this anywhere, I had to ask)

    I also hear that if you disconnect your phone line, it is still likely to remain attached to the phone company so that you can call and order service. If the phone company gets a 911 call on the disconnected line, they will still forward it to your 911 center, likely without any ANI/ALI E911 data.. (Try this at your own risk)

  7. 911 service is a red herring by Jah-Wren+Ryel · · Score: 4, Insightful

    This privacy freak is really pissed off that so many people take 911 locator service for VOIP and cell-phones so seriously. It is all just a red-herring to distract us from the fact that they are building location tracking into systems that don't need it.

    The whole 911 "problem" could be solved in a very simple way - voluntarily. Just add a dohickey to the protocol so that when calling 911 (or any other number you want to send location info to) the phone sends a chunk of data as part of the call. It is up to the phone's owner to program the phone with whatever geographic location information they want transmitted in such cases. For the safety-freaks and soccer moms some phones would come with a GPS that would automagically fill in that chunk with the most recently recorded GPS coordinates. For the privacy-freaks other phones without GPS would require that the current street address be manually typed in, at which point you could easily LIE or just leave it blank if that's what you wanted. Whatever option you choose, the owner of the phone, not the FCC nor the FBI nor the DHS should have control over what is repoted when.

    Do that, and all this infrastructure, overhead and complication just goes away, poof! But then so does the ability of the government to use the phone system as a mass-tracking device.

  8. Voip needs to attack the gold numbers next by Anonymous Coward · · Score: 4, Interesting

    The dinosaurs are still clutching like mad to the gold numbers (the ones that spell out words). And they continue the monopoly by keeping the localities separated, and the splitting the region codes. If I want to call next door, or a few miles away in the same city, I have numerous area codes to wade through (718, 646, 917 just in Queens, NY, and 212 and other codes across the line in Bronx/Manhattan). And though 917 area codes were once provided solely for pagers and cellular phones, this is no longer true, 917 area codes now include home numbers, but try telling this to a bank that refuses a 917 number as a cell number or pager number.

    VOIP should make it possible to increase the number of digits to more than 7 for a local number. And because of the numbers (skype I believe is already in millions of users and can dial out to regular lines, vonage is in the hundreds of thousands and growing, my local isp provides his own voip, and so on), it should be possible for a team of skype and vonage, possibly with no one else, to begin the process of increasing a local number from 7 to 10 or 11 digits.

    This can be done by the following: treat all 7 digit numbers as a top level number, where if 7 numbers are dialed (or 10/11 with area code), 3 or 4 zeroes are automatically added to the end; the number 212-123-4567 is automatically adjusted by skype/vonage to terminate at 212-123-4567-0000, and users can add additional lines to the base number, or their account, where additional numbers can become 212-123-4567-0010 for a second line, 212-123-4567-0329 for a fax line (spells "fax"), 212-123-4567-2355 for a cell phone (spells "cell"), etc. Users who don't want people to easily guess a fax number can choose a different random number for fax, there are 9,999 possibilities to choose from. Adding 4 digits makes spelling more words possible (a little tough to explain the hold on gold numbers, but diminishes control if you think about the added words that can be spelled).

    This would obviously take many years to make work correctly (would break old pbx) but I can make the changes now on my fax machine, most old pbxs are being dropped in favor of voip (especially as the old pbx systems break), and would be limited to skype (which breaks rfcs right now anyway) and vonage (breaks rfcs?), but others can adopt more quickly because the newer equipment can have its firmware upgraded, it isn't hard coded in like old systems, and the new voip systems are directly connected to the internet making upgrades easy (vonage box upgraded itself when plugged in initially).

    The time to add numbers is now. this can bring back area codes to some sanity (one area code for whole state would be nice, one code per county would be ok too, but one code for multi-county cities would be better than chopping up a single county into a number of area codes).

    I'm sure there are hurdles that others will point out. But skype, with the skype to skype calling, makes it possible to add numbers. If it becomes popular (and I'm betting it would), then others (vonage could do it vonage-to-vonage, vonage-to-skype, skype-to-vonage) would jump in, lest they lose business to skype.

    Adding 4 digits (or even 3) to the end of a number would cut dramatically the number of phone numbers needed. And I know small businesses would welcome consolidating fax, cell, pager, and extensions under a single number. They already do this with "hunting" on a single main number anyway. And this is being done more and more with fax numbers, where computerized phone systems make it possible to receive a fax coming in on any phone number, not just dedicated numbers like it used to be.

    POTS companies would still have control over, and be able to charge a premium on, gold numbers. But a lot of numbers would be freed under the additional digits, including what are gold numbers, but aren't being charged as such because companies have held the numbers for longer than the gold number charging has been out. And as those gold numbers migrate to oth
