ExponentHR Drives Client Service With AltiGen's MaxACD

Microsoft(R) Lync(TM) Based Contact Center Supports Service to Clients Throughout the U.S.

SAN JOSE, CA -- (MARKET WIRE) -- 04/25/2012 -- AltiGen Communications, Inc. (OTCQX: ATGN) (PINKSHEETS: ATGN), the leading provider of integrated Microsoft-based Unified Communications solutions, today announced that ExponentHR has deployed AltiGen's MaxACD contact center solution for Microsoft Lync.

ExponentHR, one of the fastest growing human resources information systems (HRIS), provides payroll and tax services, a benefit administration tool, an employee communication portal, a reporting system and more to clients via the software-as-a-service (SaaS) model. The ExponentHR platform streamlines traditional, administrative HR functions for client companies wanting to reduce operating costs, engage employees and create scalable infrastructure. The company has a history of using proprietary and state-of-the-art third-party technology to deliver client solutions that adapt to ever-changing business needs.

In 2011, the company began to replace its Cisco call center communications infrastructure with a Microsoft-based unified communication platform (Lync), a continuation of ExponentHR's commitment to deploy the latest innovative technologies that ensure efficiency and the best customer service. "Immediate availability, response and follow up with our clients and their employees are our top three priorities," said Greg King, director of client relations and services at ExponentHR. "We saw an opportunity in partnering with AltiGen as a best in class provider that could help improve these key service metrics with our customers."

The biggest challenge for ExponentHR was to find a product that fully integrates into Microsoft Lync as a software-based contact center solution. "We evaluated many options for our contact center solution before we began implementing AltiGen's MaxACD in March 2012," said Misha Vyazmensky, chief technology officer at ExponentHR. "During our evaluation, AltiGen's MaxACD call center software for Lync set itself apart from competitors with its ease of deployment, performance, reliability and its integration into Lync. With the range of capabilities, our customer service agents can use the exact applications they need to ensure the best possible support for our growing client base."

"Fast growing businesses like ExponentHR require tools to ensure great client service," said AltiGen vice president of sales Mike Plumer. "MaxACD allows companies to quickly deploy contact center capability that is advanced yet easy to manage and affordable."
