Consumer VoIP projected to hit 37 million by 2011

Boston research firm Yankee Group reported that consumer VoIP use increased by 125 percent last year, to more than 9 million subscribers. VoIP adoption in the United States reached 9 percent of households, up from 4 percent the previous year.

Ongoing demand for VoIP service is expected to intensify with the deployment of dual-mode cell phones, which numbered less than 1 million in 2006. Yankee Group expects the number of dual-mode handsets in the market to reach 22 million within four years.

Cable VoIP had the strongest growth, increasing by 167 percent in 2006. The bundled service VoIP play from cable operators is expected to dominate the market by 2011.
