The Federal Communications Commission voted Wednesday to force landline phone companies to act faster when their subscribers want to move their phone number to a rival service.

The commission will require companies to transfer, or "port," landline phone numbers within one business day, down from the current four-day requirement.

Wireless numbers are currently ported within one day -- in many cases within hours -- and the commission said landline companies should be just as fast.

Angry online subscribers who had their Web surfing habits tracked in detail are suing a Silicon Valley startup that created the technology and six Internet service providers that briefly used it.

The 15 customers who filed the lawsuit in federal court here Monday demand more than $5 million in damages and are asking a judge to turn the case into a class action representing tens of thousands of Internet subscribers.
