Although VoIP phones are gaining traction, tens of thousands of users may find their service has been cut off next week. The FCC set Monday as the deadline for users to formally acknowledge that they have been made aware of potential problems with dialing 911 over their VoIP phones. Those who fail to comply will have their service cut off until they do so. Provider Vonage said that 96 percent of its users have responded, according to this story in the Miami Herald, while Qwest claimed that only about 75 percent of its business and residential customers have made the acknowledgement in a piece that ran in the Rocky Mountain News.
