ADTRAN Expands Session Border Control to Enable Service Providers to Drive Adoption of SIP Trunking Services

Increased capacity of NetVanta 4430 and NetVanta 3430 provide scalability and flexibility to address medium and large enterprises

HUNTSVILLE, Ala.--(BUSINESS WIRE)-- ADTRAN®, Inc., (NAS: ADTN) , a leading provider of next-generation networking solutions, today announced enhancements to its popular NetVanta series. The enterprise Session Border Control (eSBC) Feature Pack has been added to its NetVanta® 4430 series, and the session capabilities of the NetVanta 3430 have been doubled. This application was designed specifically to address the need of service providers to monitor and manage their growing demand for SIP Trunking services. Because each NetVanta platform provides a single device that can support both data routing and SIP Trunking Services, either is a perfect solution for medium and large enterprises.

"SIP Trunking is a rapidly growing service type for Charter, and having the ability to scale our offering quickly and easily is an advantage," said Pete Hicks, senior director, product management, Charter Business. "ADTRAN's eSBCs provide an easy-to-manage demarcation device that handles the normalization, security and monitoring of our rapidly growing SIP Trunking service offering."

The NetVanta 4430 with eSBC Feature Pack can support up to 300 sessions while the NetVanta 3430 can now support up to 100 sessions. The expansion of the product's eSBC capabilities was in direct response to carrier demand for an efficient product set that could be used to manage, maintain and grow SIP Trunking services across a network footprint. This new capability, combined with the ability to field upgrade ADTRAN's market leading IP Business Gateways with eSBC functionality, allows ADTRAN's existing carrier customers to quickly tap into the rapidly growing SIP Trunking market.

"The ability to remotely software upgrade our industry leading installed base of IPBG's and access routers provides tremendous value to our service provider customers. It delivers a compelling and cost-effective transition path to newer services without the need to replace equipment already installed in the network," said Chris Thompson, ADTRAN's director of product management, Cloud Connectivity Solutions. "Our customers rely on us for technology to drive network efficiency and to open up new paths for service and revenue growth. The expansion of eSBC capability, in terms of capacity and across the product line, is a prime example of our ability and commitment to help providers achieve these goals."
