VoIP providers should be happy to know that awareness of their service is growing — 62% of online consumers have heard of VoIP, compared with only 43% in 2005 — but this isn't translating as quickly into purchases of VoIP. Interest in the technology persists but has remained nearly flat since 2005 at a little more than 10% of consumers. Standard messaging about low price points, expanded feature sets, and international calling plans will continue to drive awareness and interest among early-adopter consumers. But to convert mainstream consumers from awareness to interest to adoption, marketers must sell the service — not the technology — and market its reliability and the seamless transition from plain old telephone service (POTS) to VoIP.
