AltiGen Communications Expands Partner Network With the Addition of The Via Group

SAN JOSE, CA--(Marketwire - May 5, 2011) - AltiGen Communications, Inc. (OTCQX: ATGN) (PINKSHEETS: ATGN), the leading provider of integrated Microsoft-based Unified Communications solutions, is pleased to announce the addition of The Via Group (http://theviagroup.com) to its partner network.

The Via Group, founded in 1990, has a long history of providing consulting, professional and managed services, message networking, communications and network integrations. The Via Group is recognized as a global leader in providing Microsoft Unified Communications expertise to their customers. By leveraging strategic relationships with industry-leading manufacturers, The Via Group is able to provide customers with solutions that drive competitive advantage and improve business processes. Anchored by the company headquarters in The Woodlands, TX (near Houston), continued expansion has led to a national presence with employees in Atlanta, GA; Chicago, IL; Dallas/Fort Worth, TX; Jackson, MS; and Manchester, NH (Boston Area).

As one of the premier Microsoft solution providers, The Via Group continues to stay on the forefront of innovative technologies. "We are seeing a continuing shift from traditional telephony hardware and applications to communication enabled business processes and applications, like Microsoft Lync, running on standard hardware. The new trend in applications allows customers to seamlessly integrate communications into the way they do business, and achieve an ROI benefit within a very short period of time," stated David Bickford, Chief Technology Officer. "We looked at several alternatives for call center and mobility to use with Microsoft Lync Server 2010. AltiGen provides The Via Group with a solution for both customer needs, in a single server platform. We are also extremely excited about working with the AltiGen sales teams across the US to bring The Via Group's UC expertise to customers."

"The Via Group will be a great addition to our network of quality partners. Their industry expertise and national coverage offers AltiGen an opportunity to continue expanding in to the enterprise market as well as companies with multiple locations," stated Bill Glau, Director of Channel Development. "The continued adoption of Microsoft Lync 2010 is very exciting and there is clearly significant opportunity to ensure a successful partnership with The Via Group."
