DENVER, October 10, 2005 - Qwest Communications International Inc. (NYSE Q) today announced a new enhancement to Qwest?s IP voice terminating service providing operating company number-based (OCN) billing to wholesale facilities-based carrier customers. The new billing option provides pricing at the individual OCN/LATA level, giving customers the ability to easily reconcile their billing, and manage costs more effectively.

Historically, many customers paid for services using blended or averaged rates. However, with the OCN billing option for IP voice terminating services, wholesale customers will receive pricing that includes over 25,000 OCN-based rates ? allowing customers to better manage their network routing costs.

?Offering IP voice terminating services with our OCN billing solution is a telling example of how we?re designing our services around our customers? needs,? said Roland Thornton, executive vice president, wholesale services for Qwest. ?Our customers asked us for this flexibility because it provides market opportunities for them, and we?re seeing significant success as a result.?

Qwest?s successful IP voice terminating service allows customers to deliver IP voice traffic directly to Qwest for termination to the Public Switched Telephone Network (PSTN), without the arduous process of converting the traffic from IP to time division multiplex (TDM). With Qwest?s IP voice terminating service, wholesale customers do not need to purchase or manage the gateways necessary to make these conversions.
