JupiterResearch projects that the broadband telephony market will nearly double in size from 14.7 million subscribers in 2007 to 28.4 million lines in 2013. Cable operators will see most of this increase, with their VoIP subscriber base nearly doubling during the forecast period, while growth for over-the-top VoIP providers will stagnate. The emergence of new service offerings, such as those from AT&T and Skype, will continue to generate buzz within the market.
