Like just about everybody else with common sense, I can't understand BTL's obsession to block VOIP: It doesn't bring more business (telephone calls) because VOIP conversations would not be done on telephone. VIOP usually replaces email and on-line chats. It is just like stone carvers trying to ban (that devilish) paper when it was invented in ancient times.
Sorry Bud - but why else would they do it? Skype, Vonage etc came into Belize with a force in 2003ish. BTL saw their casual international phone revenue take a nose dive. Once it became clear to users that VoIP technology was stable/clear, BTL started to see their business revenue from international crumble. As a provider with a very low average revenue per user (from locals) and an even lower user base, this was a problem. Did you know that telco companies in Belize pay 19% GOB tax on all revenue? Imagine US$20 million leaving BTL in the form of VoIP switchers - which is a very reasonable number. Almost US$4 million in lost tax revenue. This is why the government has never done a thing about VoIP blocking...
I'm not saying it's right, but don't fool yourself. It is ALL about the money.
