Bandwidth.com and CompUSA Choose Covad’s Voice Optimized Access for their VoIP Offer

San Jose, Calif. (March 20, 2006) - Covad Communications Group, Inc. (AMEX: DVW), a leading national provider of integrated voice and data communications, today announced that it has been chosen to be a preferred DSL and T-1 provider to Bandwidth.com for its voice over IP solution, to be sold through an agreement with CompUSA.

“We are very pleased to be a preferred provider to Bandwidth.com as it partners with CompUSA to launch this exciting new voice solution,” said Lisa Graham, vice president of wholesale sales for Covad. “Covad has a strong relationship with both companies and we look forward to helping them succeed in this venture.”

Under the terms of the partnership announced at the Spring 2006 VON Conference last week, Bandwidth.com will launch its voice over IP solution targeting small businesses through CompUSA’s retail locations, commercial sales and website. The service is a fully hosted IP telephony solution that incorporates Bandwidth.com’s robust platform and feature set and will be available over Covad T-1 and SDSL voice-optimized access (VOA). CompUSA will launch the service in April 2006. Covad has been providing Bandwidth.com with T-1 and DSL services under a wholesale arrangement since 2002.

“Covad has a proven track record serving business customers and we are delighted to be offering Covad services to CompUSA customers,” said Henry Kaestner, CEO of Bandwidth.com.

Covad’s VOA enables small business customers to conduct multiple phone calls and access large data files concurrently over the same connection without compromising the quality of their voice services because Covad controls the flow of voice traffic over its nationwide network and prioritizes telephone conversations over data traffic.
