Forrester surveyed 1,132 online US households to gauge their awareness and interest in services based on VOIP technology. 43% of our respondents had heard of VoIP before taking the survey, with word of mouth as the biggest driver of awareness at 23%. But awareness did not translate into sales because a mere 3% are using a paid VoIP service and 1% are using a free service. Only 13% are interested or very interested. With somewhat interested users, the total barely breaks 36%. When asked why they aren't interested in VoIP, more than 60% of consumers said that they are satisfied with their existing service. 50% also feel their services are reasonably priced.
