America’s three largest incumbent telecom operators, AT&T, Verizon Communications, and Qwest Communications International, have agreed to work together in an effort to prevent cable rivals from poaching their landline telephone and DSL subscribers.

When customers relocate outside their current carrier’s service area, the carrier will refer them to a new website called Movearoo.com, which helps them smoothly switch to a new residential telephone offering, but does not include information on VoIP or cable phone services.

The jointly-operated website encourages subscribers to remain within the traditional telephone fold, and is intended to maintain the fixed-line customer bases of all three companies. Some 60% of residential customers rethink their telephone customers when moving, according to recent data.

America’s leading fixed-line operator, AT&T, currently offers home telephone services in 22 U.S. states, including most of the Southeast and Midwest. Its closes rival, Verizon, has a fixed-line presence in 25 states, primarily in the Northeast, while number-three carrier, Qwest, offers local lines in 14 Western states.
