Thousands of VoIP users are set to be disconnected Monday under a recent FCC ruling regarding provisioning of enhanced 911 service on VoIP lines.

Under the FCC ruling, interconnected VoIP providers, that is those who provide connections to the public switched telephone network, allowing them to have normal telephone numbers, were required to notify all of their users about the availability of enhanced 911 service, and that the service may be unavailable during a power failure or loss of Internet connectivity.

Which is completely stupid, but hey, it’s the government, and the planet is full of stupid people who apparently don’t realize that their little VoIP adapter box needs both power and an Internet connection.

Anyway, the ruling requires that subscribers respond back, affirming that they understand the limitations of 911 on VoIP. Anyone who has not responded as of August 29 is to have their service disconnected until such time as they do respond.

Vonage told the Associated Press Wednesday that 96 percent of its subscribers had responded to the notice, but that leaves 31,000 subscribers who have not. Other VoIP providers, such as AT&T, face similar situations.

Now this is pretty simple. You go to your carrier’s web site, you sign in, you fill out the E911 form, and you’re done. Go do it this weekend if you haven’t already.

Update: The FCC announced today that it is extending the deadline to September 28. You should still get your E911 acknowledgement in as soon as possible.
