According to a story in Information Week, Forrester Research did a survey that discovered only 13% of consumers are either "interested" or "very interested" in using Internet telephony sevice. The survey - "Who Wants to Buy VOIP" - found only 3% of consumers are using Internet telephony. The biggest hurdle appears to be price: consumers want to see savings of at least US$15 to US$25 a month before they jump from traditional telephone service.
The good news for service providers is consumers who actually use the technology like it 90% are happy with pricing, 80% like the features and 70% are content with the voice quality and billing. Forrester estimates Vonage is the leading player with 30% of the U.S. market, while Skype and Cablevision each have 13%.
