Cricket Jumps on the Benefits of VoIP Peering with Acme Packet.

Acme Packet Session Border Controllers Enable Cricket to Drive Down Costs and Speed Time to Market with Trusted VoIP Interconnects

BURLINGTON, Mass. -- Acme Packet[R] (NASDAQ: APKT), the leader in session border control solutions, today announced that Cricket Communications, the operating subsidiary of Leap Wireless International, has deployed Acme Packet's session border controllers (SBCs) to securely interconnect its VoIP core network to other service providers. Cricket is one of the first mobile operators in the United States to interconnect its VoIP core via IP to other service providers for PSTN origination and termination.

Cricket is a simple, affordable wireless service offering consumers and local businesses a flat-rate, unlimited service utilizing the latest infrastructure technology. Cricket offers service in 23 states and has more than three million customers. Designed for customers whose basic and advanced wireless needs have not been met by traditional communications companies, Cricket is the pioneer of unlimited services with no long-term commitments or credit checks required.

After initial Acme Packet Net-Net[R] 4000 Session Director deployments in 2006, Cricket is now expanding with the deployment of Acme Packet's Net-Net 9000 hardware platform, in multiple points-of-presence (PoPs) to meet the increasing traffic demands as Cricket's subscriber base continues to grow. Acme Packet's Net-SAFE[R] security architecture features denial of service (DoS) attack prevention, access control lists and signaling rate limiting, providing security and assured network availability for Cricket's VoIP interconnects to various business partners. Acme Packet's SIP call routing and load balancing features distribute voice traffic to peering partners, ensuring service availability, while its QoS marking and mapping of in-bound calls enable priority treatment for assured call quality. Cricket also uses the SBC accounting features for billing and network planning.

"For Cricket to succeed in a highly competitive mobile marketplace, our network design called for minimal capital expenditures while leveraging a high-quality, state-of-the art all-IP core," explained John Saboe, vice president of engineering at Cricket Communications. "This allows us to interconnect with other service providers via IP, optimizing operational aspects such as time-to-market and costs. Acme Packet's SBCs offer unmatched performance along with the security and control features we required to realize our goal for secure VoIP interconnects."

"Cricket is a proven innovator and provides its subscribers with compelling mobile voice and data services," said Seamus Hourihan, vice president of marketing and product management for Acme Packet. "With our session border controllers, Cricket is leveraging VoIP interconnects to enhance its ability to rapidly innovate while reducing costs."
