There are some simple workarounds for port blocking a little later in the post:

Much of the discussion about VoIP has been centered around the challenges of port blocking, an increasingly common practice among Internet service providers. For those of us conversent in firewalls and router configuration, it is relatively simple to block VoIP traffic - as long as we know which port that traffic is using. In the U.S., this dialogue has been centered around VoIP provider VONAGE, but VoIP companies like Skype are also susceptible to port blocking. More pernicious is the practice of dropping packets and reducing performance to make VoIP an impractical alternative for enterprise applications.

There is currently no legislation on the books in the United States - or any other country for that matter - that protects VoIP traffic on an Internet connection from a public access provider. This holds true for home office workers using xDSL or cable modems; traveling workers accessing the Internet over a public Wi-Fi hotspot or a hotel broadband connection; and workers using a wide area packet data service like GPRS/EDGE, EV-DO or any other 3G offering.
