According to published reports, residential VoIP subscribers are expected to dramatically increase in number spurring revenues for VoIP equipment to more than triple between 2004 and 2010. This prediction comes to us courtesy of iSuppli.

According to the El Segundo-based research firm, “the number of residential VoIP subscribers worldwide will rise to 197.2 million in 2010, up more than 40-fold from 4.8 million in 2004. The significant jump will help drive worldwide wireline VoIP equipment revenues to $24.5 billion in 2010, more than three times the $8.04 billion in 2004 sales. In 2005, VoIP equipment revenues will rise to $12.9 billion, up 60% from 2004.”

iSuppli predicts that the residential segment will be the fastest-growing portion of the entire VoIP equipment market, with revenues expanding to $10.6 billion in 2010, up 650% from $1.4 billion in 2004. The firm also believes that Japan and the United States, which today comprise about 83% of the overall residential VoIP market in terms of consumers, will continue to lead subscriber counts, and by 2010 the two nations will account for over 56% of all VoIP subs.
