Four businesses, including a St. Louis-based firm, will pay a total of $100,000 for violating Missouri's No Call list, Attorney General Jay Nixon said Thursday.

The four businesses that violated the law by making telemarketing calls to Missourians on the list are DIRECTV Inc., Blue Sky Network Corp., Trio Mortgage and The Debt School, according to a release from the attorney general's office.

DIRECTV will pay the most of the four, with a $50,000 fine. The El Segundo, Calif.-based firm is the largest provider of direct broadcast satellite services in the country.

Blue Sky Network Corp. of Reno, Nev., will pay $30,000 for making calls to consumers, surveying their interests in real estate. Trio Mortgage of St. Louis will pay $5,000 for making calls marketing mortgage loans and related services to consumers. The Debt School of Weston, Fla., will pay $15,000 for making calls marketing debt counseling services to consumers.

Since the No Call law went into effect July 1, 2001, Nixon's office has collected more than $1.8 million in penalties from businesses that violated the law, according to a release.

More than 2.3 million residential phone numbers are currently registered on the No Call list maintained by the attorney general's office. The list is updated quarterly and made available for telemarketers to purchase to ensure they don't market to numbers on the list. The deadline to add new numbers to the list under the Jan. 1 update is Nov. 1.
