Announces Unlimited Domestic Monthly Minutes for VoIP Customers Using PBXi PlusCovad Communications Group, Inc. (AMEX:DVW), a leading national provider of integrated voice and data communications, announced today that its PBXi Plus business-class Voice over IP (VoIP) product has just received a 2005 Product of the Year Award from Technology Marketing Corporation's Communications Solutions magazine. Covad also announced that it has made this award winning service even better by providing its new and existing PBXi Plus customers with unlimited domestic monthly minutes.(1)

"With this enhancement, PBXi Plus becomes an even better fit for how small and medium businesses use VoIP," said John Grady, director of product management for Covad. "PBXi Plus provides customers who have already invested in a premises-based telephone solution an unbeatable value combination: award winning VoIP technology, the quality of service (QOS) of Covad's nationwide network, a seamless installation experience and no upfront charges."

Covad's PBXi Plus targets small businesses and distributed enterprises that have existing on-premises phone equipment. The product integrates seamlessly with business phone systems because the business is able to retain its original handsets, phone numbers and equipment. PBXi Plus requires no upfront expense: Covad provides a professional installation and Cisco 2431 router at no charge. Full e911 service is included.

PBXi Plus runs over Covad's Voice-Optimized Access (VOA) T1 lines. VOA allows Covad to manage the quality of both voice and data services simultaneously, and enables our customers to realize significant cost savings, while eliminating the expense of maintaining separate voice and data networks.

The product is based on the Covad hosted platform and supports the functionality of the customer's existing PBX system, but adds other valuable features, including new online management and configuration capabilities. Covad also offers a hosted business-class VoIP product, Covad vPBX, for customers who are replacing existing premises-based solutions in favor of the convenience and reliability of a fully-managed VoIP solution.

No action is required for existing PBXi Plus customers to take advantage of the increase in monthly minutes: the service plan upgrade will be reflected in their June invoices.Minutes are capped at 101,000 minutes per month per site. Covad charges approximately $0.025 per minute for any usage above the 101,000 minute cap.
