VoIP will spill over into mainstream US residential household and businesses by 2006, according to a new eMarketer report. Currently, the number of US VoIP subscribers is small, with varying estimates predicting between 2.8 million and 6.7 million residential VoIP lines in use by the end of 2005. In five years’ time, even the most optimistic forecast predicts just 27.0 million residential VoIP subscribers, accounting for 19.6% of the 137.4 million US consumer and small business wireline subscribers at the end of 2003.
