Infonetics, an international market research and consulting firm covering the data networking and telecommunications industries, is set to release a research report tomorrow covering the cable VoIP market.

According to the report, Cable VoIP Equipment Market Outlook, the number of cable VoIP subscribers in North America jumped 900% between 2003 and 2004, from less than 50,000 to close to half a million, while cable broadband subscribers grew 26%, from 17.7 million to 22.4 million.

The latest Infonetics report posits that North American cable companies increased their investments in VoIP equipment to keep up with surging subscriber growth, nearly doubling their spending between 2003 and 2004, from $63 million to $123 million. The company’s forecasts indicate continuing strong growth.

Said Kevin Mitchell, directing analyst for Infonetics and author of the report, "Although the number of cable VoIP subscribers is still fairly small and two MSOs made up over 90% of that subscriber total in 2004, we expect the penetration of VoIP service delivered directly from MSOs among cable broadband subscribers to increase from 2% in 2004 to 15% in 2007."

The Cable VoIP Equipment report tracks cable broadband and cable VoIP subscribers, media gateways, media servers, session border controllers, softswitches, voice application servers, and EMTAs, providing annual equipment revenue and subscriber forecasts through 2007.
