SBC Communications (SBC) , one of the country's biggest local telephone companies, filed with federal regulators for permission to offer long-distance telephone service in Missouri.
SBC was one of the local phone companies created by the break-up of AT&T. The Baby Bells can't offer long-distance service until they prove their local networks are open to competition.
The company, which is based in San Antonio, Texas, has already received approval to provide long-distance in Kansas, Oklahoma and Texas.
Shares of SBC, a component of the
