CyberTel gears up with the US Troops. This is really nothing more than a play on the calling card/pre-paid idea. With handsets that connect to a PC via USB and SIP this is not that hard to do. What makes this meaningful is the need is there and this saves the soldiers money.
On the flip side, if a soldier is PC enabled and can download Skype, then this is meaningless, because with Skype and a headset the call is free.
