1 mln Americans buy VOIP, 160 mln have landlines, 170 mln have cell phones

The number of home VOIP lines in the United States was roughly 1 mln at the end of 2004, a drop in an ocean compared with about 160 mln landline and 170 mln cellular phone subscribers. But some estimates say VOIP subscribers could triple this year, thanks largely to cable company campaigns to sign up phone customers, and hit 20 mln by 2008. Other countries that have more widespread broadband use have seen faster VOIP growth, with Japan’s Yahoo Broadband the largest provider so far at 4.4 mln VOIP lines.
