WorldCom claims it has met legal and regulatory requirements for call routing, contrary to claims made by AT&T, following its own internal analysis.
The company, now operating under the name MCI, filed a response in the US Bankruptcy Court to AT&T's complaint filed last week. Those claims came in the form of an objection to WorldCom's restructuring under Chapter 11 bankruptcy.
Other carriers have joined AT&T in complaining that the company routed calls improperly in ways that allowed it to make smaller access fee payments than required. AT&T was the only carrier to file an objection in bankruptcy court.
The MCI filing called AT&T's charges baseless and "demonstrably false" and charged they are designed to derail MCI's reorganisation plan. MCI called AT&T's actions a "misuse of the bankruptcy process".
It also predicted further efforts to obstruct its reorganisation efforts and urged the court to view the tactics in the "highly charged competitive environment evident in this case".
MCI said its contract with one smaller carrier, Onvoy in Minneapolis, for least-cost routing services was "completely legal and commonplace". That agreement included routing US calls through Canada and back again.
MCI's analysis of call routing continues.
