Mississippi regulators have ordered a company named Tailbone Security to pay $420,000 for violating the state's ban on unwanted telemarketing.
Commissioners voted to impose the penalty against Tailbone, which is based in Boynton Beach, Fla.
It's the latest in a series of large fines that the Public Service Commission has issued for companies that violate the state's prohibition on calling people who have registered their phone numbers to get telemarketers to stop calling.
Commissioners say Tailbone also violated Mississippi's prohibition against telemarketing robocalls, using an automated dialing system to make recorded phone calls.
The commission's penalty is a civil fine, not a criminal action.
Last year, Mississippi regulators levied a $5.7 million fine against two Arizona companies and their directors.
