We've told you how mobile phone companies have been suing the annoying culprits behind the automated extended car warranty calls that plague us morning, noon and night. 

Well, in a complaint filed in an Atlanta federal court, AT&T Mobility has named a Maryland company, Volcano Leads, as one of nine responsible for millions of these calls during just a few months.

Justin Ramsey, the owner of Volcano Leads, denied the allegations when reached yesterday by business reporter Lorraine Mirabella, saying his business never owned an auto-dialer.

AT&T says the companies violated the federal Telephone Consumer Protection Act, and hopes to prevent them from making future calls, as well as fining them $500 for each violation of the act.

See below for a copy of the complaint as well as a sampling of the numbers they were calling from --- perhaps they are among the ones you've set to silent ring tones!
