Market research from Telegeography shows that the VoIP market in the United States is still growing at a healthy rate, and that the market in Europe is growing even more quickly. This is happening despite the recent difficulties of companies like Sunrocket and Vonage.
The research shows that cable TV companies are responsible for much of the increase in subscribers, while large telcos are still considered to be on the sidelines. That will no doubt change in coming years, as those telcos embrace IP.
