Carrier Access Corporation (Nasdaq: CACSE), a leading provider of broadband communications equipment, and Acme Packet(R), the leader in Session Border Control (SBC), announced compatibility between Carrier Access Adit(R) 3104 Business Gateway and the Acme Packet Net-Net(R) session border controllers. As a result, service providers will be able to easily deliver enhanced Voice-over-IP (VoIP) and other real-time interactive IP-based services and applications to business and government users.

Additionally, the companies confirmed two mutual service provider customers are currently in trials with the same configuration.
