VoIP for Deployed Soldiers?

rickbassham asks: "With VoIP really catching on these days, I decided to look into it for keeping deployed soldiers in touch with family and friends. I am currently a soldier in Iraq, and have the ability to get satellite-based internet, thanks to a few of the locals. While individually it is prohibitively expensive, a group of soldiers can come together to purchase a decent-to-high-speed internet connection. One of my plans is to link other soldiers to Vonage or another VoIP provider, so they will be able to keep in touch. Understanding the latency issues with VoIP via satellite (not to mention the other disadvantages), what upload speed does Slashdot recommend as a minimum for a QoS enabled connection for about 15-20 soldiers? The same for a non-QoS connection? What recommendations do you have for a good VoIP provider?"

  1. Don't know where this guy is stationed but... by garcia · · Score: 4, Interesting

    I don't know about this particular solider but I have had no problems contacting three friends that were/are deployed in Iraq via the Internet. One was on AIM for 45+ minutes a day and another is on AIM for several hours a day. The third isn't quite as Internet saavy but routinely sent emails and pictures at least weekly. Granted they aren't on 24/7 like we are here but I had no problems contacting them via the Internet.

    I would like to know if I was experiencing something that is unusual for military personnel deployed overseas? I mean this guy makes it seem as if he's hanging on to a rope thrown to him by the locals. From what I understand from the one guy I know that just returned from Iraq the locals over there want absolutely NOTHING to do w/the military personnel stationed in the desert.

    I also know that phone calls were routinely made to his family and to another buddy that is stationed in the States. Why would they need VoIP and why would they need to do it via satellite connection?

    As this guy said, sat-based Internet SUCK HARD for VoIP being that it is so latent. That wouldn't exactly make for real-time conversations regardless of how clear the voice might be... I have run the testers that other slashdotters have linked to before (sorry don't have it on-hand right now) and my 256k upstream seems to rate just fine. I haven't actually used VoIP though so I really couldn't tell you and I certainly couldn't recommend something to handle 15-20 people simulatanously (if that's what you mean).

      Once again, it depends on where you are stationed. I, personally, work in a Node Center switching shelter which basically serves as a telephone switch hub where I can call 'out' to phone centers ran in the US who then transfer me to whomever I want for free. Friends of mine get more time than normal people that wish to use this service, of course, as I'm the one running the switch. Other places in Iraq aren't so lucky and must pay sometimes up to $5 a minute for calls to their family. I know that it's not fair, but some places obviously can't get everything due to the availability of attacks.

      As a soldier, I thought I'd shed some light here.
      The cost to phone home isn't much at all, actually. For about $40 you can get like 1000 minutes. I can only speak for the Air Force, here, but we can also call the base operator at the base we are stationed out of and have them dial our loved ones. Technically we only get 2 of these calls each week and they're supposedly limited to 15 minutes, but often if the phone center isn't busy and/or your base operators are understanding, you can get more calls and sometimes stay on the phone longer. I remember several times I got to talk to my fiance for an hour or more, for free.

      That is misleading for two reasons. First, the signal does not travel through the planet, it travels around the surface. Second, your calculation is for sending a signal (and receiving an echo) from opposite sides of the planet. Should I not be able to expect a shorter ping time if I am pinging my next door neighbour? Google says: (10 meters * 2) / the speed of light = 66.712819 nanoseconds.

      This might be a good starting point. Baghdad, Iraq to Washington DC, United States is about 9968 km, yeilding a 66.5 ms minimum ping time.

  4. Okay Idea.. Wrong Tech by IcEMaN252 · · Score: 4, Interesting

    Sat-Internet usually uses GEO satellites, so as you say its really not good for latency sensetive applications, ie. VoIP.

    But, if you're thinking about pooling resources, what about some type of satellite phone? Most sat-phones use LEO satellites, so latency isn't a problem. Its true, they are expensive, but if you are pooling resources, it might make it affordable and provide a better quality of service.

    Of course, I'm not a soldier, nor do I personally know one, so I can't speak to what's really reasonable there. Also, I'd be curious to know what regulations the military has about personal communications equipment.

    Back in the day, when I was stationed overseas, the cheapest way to call home was a service that was hosted by ham radio operators. We'd call up the local ham who would transmit to a us-bound operator who would make the local call to the family. It was always weird talking to your mother to say things like "How are you doing?

  10. Grunts phreaking military comm systems by billstewart · · Score: 2, Interesting
    So back in the mumblety-late-60s, a buddy of mine was working communications at Offutt AFB, home of the Looking Glass weapons-of-really-mass-destruction flying control center. The Looking Glass bird had a small PBX on board to connect users to each other and to the rdio uplinks from the ground. You can get to that PBX by dialing the right phone numbers on the base PBX. The military had a private worldwide phone system called AUTOVON that had interesting features like call priority and preemption.

    One day somebody on the bird saw two red lights on on the PBX, but didn't see anybody talking on the phone, and needless to say this was .... disturbing.... So they went to track it down - some grunt had gotten a 16-button Autovon phone (with the extra precedence TouchTones) and had dialed the base PBX, dialed up to the bird's PBX, dialed across it to an outgoing line back to the ground, which needless to say had permission to call anywhere in the world at any priority it wanted, and was yakking with his buddies in Guam (normally something a grunt didn't have authorization to use routine scarce resources for, much less tandem-routing through Looking Glass. He was very busted.)

    The Offutt PBX also had an FX line to somewhere a few hundred miles away like Des Moines - if Bad Things were happening in Omaha, you could access it remotely, and folks on the bird could use it to call out and find if people were Not Dead Yet.

    That was one of the more disgustingly false pieces of drivel I've had the misfortune of reading in a long time. It doesn't deserve a rebuttal, but neither can it be left unanswered.

    A soldier doesn't just kill or be killed. Soldiers have objectives that span the gamut from destroying to rebuilding, and from killing to healing the sick and wounded.

    A soldier doesn't give up his family or friends. For many a soldier, his family is the single most important part of his life. The desire to return home to resume a life with those same family and friends can be the single most motivating force.

    A soldier doesn't give up a career. For some, the military is a career, for others the military is the first real job they've ever had. At most, a reservist will have his career put on pause during his active service.

    The soldier that only understands killing is a very bad soldier indeed. Such a soldier doesn't pay attention to the many shades of gray between friend and foe, nor to the extremely important distinction between minimal and maximal force.

    Yes, war changes people, in ways that are powerful and profound. And no...you will never be quite the same person afterwards. But love and friendship also change people irrevocably. Many will find mental and emotional trauma on the battlefield, and many will become stronger from the experience.

    As far as the specific issue of the phone, you have no understanding of history and war if you don't recognize that communication with one's family and friends at home has been a staple of the soldier's life as long as there have been ways of sending those commmunications.

    I pity the soldier who has no interest in communicating with his loved ones, for there is a lonely soul indeed.

    And I pity you because your astonishing failure to understand humanity and the human condition make you a very very small-minded person indeed.

  13. Communication in Iraq by StWaldo · · Score: 2, Interesting

    During my last deployment to Iraq (and surely, during my upcoming one) we had a number of communication options, ranging from cheap to pricey, crappy to great.

    The first mode I was introduced to is free for most soldiers. It's called DNVT (don't ask me what it stands for, I'm not a commo guy). Basically it's a phone that connects either through hard-wired connection or via a line of sight radio connection. It's relayed through to the military's DSN network (a military-only phone system) where you can call any military facility in the world. Up to this point it's free, but notoriously spotty, mainly because of communication priorities of different units (my squadron had lower pri vs. our regiment), and that "morale" calls have low priority as well (keep in mind, these commo networks are used for operational needs primarily).

    Once you contact the military base of your choice, the operator on base can connect you with any local number for free, or with a long distance operator for collect or calling card calls. (For a good example of this in reverse, watch Heartbreak Ridge.

    The second option is through a satellite phone. Several providers are available out there, from AT&T to Thuraya, and they're all expensive.

    The third option is through an AT&T call center, which is basically satellite as well. More expensive than the DNVT, but not too bad.

    The fourth option was actually VOIP through Segovia, which was paid for through the military. Segovia provided a satellite internet connection for various FOBs (forward operating base), plus set up Cisco VOIP phones. You had to buy minutes through Segovia , but it worked out to about $.05/minute. Reliability was a bit of an issue. If bandwidth or the connection crapped out, calls either became unintelligible or just didn't go through in the first place.

    Many comments have been made that communication home should be free, and in a lot of places it is, just not high quality or convenient all the time. Some units provide video tele-conferencing for their soldiers, when available, so they can talk "face to face" with their families. Commanders realize how important communication with "the rear" is, and by and large make every effort to make that happen. Plus, many organizations provide free calling cards to soldiers.

    But I'd agree with most posters that every effort should be provided to maintain communication with the homefront for our soldiers.

    I'm using http://www.packet8.net/ for my VOIP. Their tech support says that the latency shouldn't be greater than 300ms for effective use. My latency is usually between 900ms and 950ms. As long as it's under 1000ms, the call quality and voice delay is fine if not better than using POTS.
