inContact Selects Sonus Networks For IP Network Expansion To Support Growth In Software-As-A-Service Offering

The Market Leader In On-demand Call Center Software Chooses Sonus Network Border Switch For Access Session Border Control And SIP Trunking Interconnect

WESTFORD, MA, February 11, 2010 – Sonus Networks Inc., (Nasdaq: SONS), providing network transformation through IP communications technology, today announced that inContact, the market leader in on-demand call center software and call center agent optimization tools, has chosen Sonus to expand its IP voice network and secure SIP trunking to IP-PBXs. The Sonus solution will offer scalable border security for IP connectivity as well as leverage the Sonus platform’s centralized routing and diverse media support to better manage the growing amount of traffic that crosses the inContact network.

inContact is a cloud-based application provider that eliminates the need to install complex and expensive contact center software and hardware on the customer premise. Instead, customers use their feature rich contact center platform in the cloud from inContact. This enables customers to pay only for the services they use and have the ability to scale the solution to meet changing demand. inContact is deploying the Sonus next generation components that will centrally manage policy, routing and security on the inContact network. This will set the stage for inContact’s global network expansion.

Supported by the Sonus Networks Global Services team, inContact will implement a network project that will reduce their investment in existing IP network solutions, consolidating future investment around the Sonus solution. inContact will be able to maximize its investment in existing infrastructure, while providing seamless migration to the Sonus IP based network.

“We made a strategic decision to expand our SIP capabilities to position ourselves for the market opportunity,” commented Scott Welch, chief operating officer of inContact. “We wanted to better support SIP trunking and still have the ability to support traditional TDM connections, while reducing the number of equipment vendors in our network to gain greater efficiency in management and interoperability. During our rigorous selection process, we were impressed by the efficiencies gained by Sonus’ ability to provide session border control and media gateway capabilities on the same element. The Sonus solution, which can manage IP and TDM traffic across the same network, combined with the SIP interoperability made Sonus the right choice to provide leading service to our customers.”

“inContact is offering a new way for call centers to increase their efficiency and productivity, providing not only carrier class connectivity but the tools required for highly efficient call center agents,” commented Mohammed Shanableh, vice president, worldwide sales for Sonus Networks. “By growing its SIP capabilities with Sonus, inContact will be able to offer new enhanced and revenue generating services to its growing customer base and continue to innovate ahead of the competition.”

inContact will deploy the Sonus GSX9000™ Media Gateway, the Sonus PSX™ Call Routing and Policy Server, the Sonus Insight™ Element Management System and the Sonus Network Border Switch (NBS) for enhanced border security, media transcoding and advanced IP peering capabilities.
