Great! could you clarify,
"Recently, voice over ip (voip) toll-bypass has been prevented by ISP’s
that block out voice over ip ports that are being used to carry voice
over ip calls thru their network. Vonage has sued the local ISPs have
won." - http://www.voip-start.com/voice-over...oll-bypass.htm

Does that mean ISP's are allowed to block VoIP calls? Is that by port
blocking or some other means?

In the U.S., the answer would be no. One ISP that did do this was
"fined" $15,000 by the FCC.

Generally speaking, it is an ISP's interest NOT to block calls, the
rationale being that the more utility (value) the customer finds in the
IP conectivity being provided, the more they are willing to pay. BUT...
When when the ISP is also in the business of delivering traditional
telephone service, you see this kind of thing attempted in order to
preserve what are often monopoly positions on that service. In many
cases, the measures taken are far more serious that merely blocking
ports. For example, recent reports have stated that Mexican authorities
have arrested two Vonage employees for transporting telephone traffic
out of Mexico without the proper "concession" (failing to grease the
right palms). The U.A.E. also plays serious hard-ball with those who try
to circumvent their monopoly, jailing would be competitors.

.... just wait, and see what AOL will do to Skype, Asterisk, and everything
else that won't match their new service, once attempting to run over their
network:
