AT&T has filed a lawsuit against MCI and Onvoy, alleging the two companies have cost AT&T tens of millions of dollars by rerouting US telephone calls through Canada in an effort to stick AT&T with termination charges.
The lawsuit seeks damages from MCI and Onvoy for alleged violations of the US Racketeering Influenced and Corrupt Organization Act (RICO).
AT&T alleges that Onvoy and MCI, engaged in a scheme of rerouting calls originated by MCI customers onto AT&T's network, so that AT&T would have to pay local telephone carriers for the cost of completing those calls.
AT&T's lawsuit does not include a specific sum because the company is still trying to determine the impact of the so-called "Canadian Gateway Project", said Jim Byrnes, a spokesman for the company.
But AT&T alleges its losses are in the tens of millions of dollars since MCI filed for bankruptcy in July 2002. The lawsuit covers only the time since MCI filed for bankruptcy, because the company's finances before then are controlled by the bankruptcy judge, Byrnes said.
In late July, US Attorney's Office for the Southern District of New York disclosed that it was investigating MCI after AT&T and two other long-distance companies had accused MCI of using the rerouting practice since July 2001.
According to MCI, its internal review has found nothing wrong in its dealing with Onvoy, accused by AT&T of helping MCI reroute calls.
MCI has suggested that routing phone calls to take advantage of the cheapest line charges is a common practice in the telecommunications industry.
Onvoy chief executive officer Janice Aune said the company had expected the AT&T lawsuit as MCI heads into bankruptcy hearings which begin on 8 September. Aune has predicted that the AT&T allegations will be dismissed.
In August, Onvoy announced it had launched its own internal investigation.
AT&T's lawsuit alleges fraud, civil conspiracy, racketeering conspiracy and other claims through a pattern of mail and wire fraud.
AT&T insisted that the conduct by MCI and Onvoy is not similar to legitimate routing practices used in the telecom industry.
While legitimate routing allows long-distance carriers getting the lowest access fees knowingly offered by other carriers, MCI used deception to pass access fees it should have paid onto AT&T.
"MCI improperly deceived AT&T into paying millions upon millions of dollars in terminating access costs that were rightfully MCI's obligation," AT&T said.
AT&T said it is trying to protect the interests of its shareholders, who were "victims of this fraud", by filing the lawsuit. AT&T's lawsuit also accuses a number of other unknown telephone companies - called "John Does 1-20" in the lawsuit - of helping MCI reroute phone calls.
