Dellsweig has provided some good points to consider.
This is funny, I am usually a
Vonage critic, NOT a
Vonage defender. (This relates to business plan, not to their service).
However, I think that your title
"Is Vonage a scam?" is rather inflammatory, borderline libelous.
Vonage has millions of customers, and
is the largest independent VoIP operation. By independent, I mean not run by a
cable company, and not run by a
major telco.
Vonage certainly has some
customer turnover, but the fact remains that they have a very, very
large number of customers.
VoIP quality issues are also in many cases
related to your ISP. Is your
ISP Optimum/Cablevision, which often has problems?
How do you fare on:

http://www.pingtest.netThose problems relate to your ISP, not to Vonage.
PS: If things got bad after your
number ported,
this perhaps is a CLEC issue, and again,
talk to Vonage customer service.
