    Further, to quote Scotty, "ye canne change the laws of physics"

  2. Re:VSAT vs dedicated satellite on VoIP for Deployed Soldiers? · · Score: 1

    I omitted to mention, and at the risk of being overtly commercial, we offer our own very reasonably priced voip-pstn termination over our IP. All you need (in Iraq) is an ATA or softphone.

  3. Re:Don't know where this guy is stationed but... on VoIP for Deployed Soldiers? · · Score: 2, Interesting

    no chance, mainly due to sanctions. There was an ISP during Saddam, Uruklink, a wholly Saddam government owned and controlled (ie filtered) provider. dont know if they allowed or blocked slashdot. We got in there in May '03 and started operations.

  4. VSAT vs dedicated satellite on VoIP for Deployed Soldiers? · · Score: 1

    I saw this post and felt I should reply to address some misconceptions about voip and satellite. As CTO of an Iraqi ISP http://www.tigrisnet.net/ who offer wireless broadband service throughout Baghdad and Basra, I have many customers who are like you, groups of soldiers who got together to buy a connection for their barracks.

    Our wirless broadband is fed by dedicated bandwidth over C-band satellite so the latency to our NOCs in downtown Baghdad and Basra is around 550ms but absolutely constant and reliable at that rtt, unlike VSAT services which are normally heavily contended and can indeed show wildly varying ping times in the 1000-2000ms range, indeed very bad for VOIP, either SIP or skype wont like that.

    Of course round trip time is twice the delay that will affect voice calls, as voice delay is only the "throw" from my phone to your phone for a RTP packet. So around 1/4 sec of one-way delay makes for very acceptable voice quality.
