From the Globe and Mail: VoIP in the US is growing faster than anticipated:

The biggest factors in the numbers are cable TV companies, which are using VoIP to bundle phone service with their TV offerings in hopes of staving off competition from incumbent phone companies that are just beginning to get into the TV business.

Time Warner Inc.'s cable division is now the nation's second-largest VoIP carrier, trailing only Vonage Holdings Corp., one of the earliest commercial providers of the service. Vonage is estimated to have 750,000 U.S. subscribers, more than three times its level a year ago.
