Cruise ship cell phone rates?

On my Regent Baltic cruise, I used straight SIP and it worked. Given what they charge (by the minute) for cruise ship internet, I'm shocked that they block VOIP. Oh well, anyway to gouge you

I found IAX2 is blocked less than Skype/SIP and fring. TMobile USA's UMA protocol is very hard to distinguish if IPSEC. It is a subspecies of IPSEC and looks similar to a commercial VPN. There are also very few subscribers so it lacks the critical mass needed for the blocking technology companies to invest much time in. If you have a iPhone, VOIPBuster has a VOIP app designed to work in the Middle East. VBuzzer has an Android App designed for the Middle East. SIP Droid on an Android running through a free VPN courtesy of PBXES.com works nicely with a free Google Voice account for free calls.
