AltiGen Communications Grows Reseller Network by Partnering With Sikich

SAN JOSE, CA--(Marketwire - September 9, 2010) -  AltiGen Communications, Inc. (OTCQX: ATGN) (PINKSHEETS: ATGN), the leading provider of integrated Microsoft-based Unified Communications solutions, is pleased to announce the addition of Sikich LLP (www.sikich.com) to its partner network. Sikich is an accounting, tax and business technology consulting firm providing services to thousands of companies and organizations in government, construction, manufacturing, professional services and not-for-profit organizations across the Midwest. With a reputation for excellence and strong, enduring relationships, Sikich redefines the way business is done.

Over the past three years and throughout the toughest of economic times, Sikich has been growing at an incredible pace. As a result, Sikich is doing more telecommunications consulting than ever before. With a reputation for excellence, Sikich needed a solid Unified Communications product to offer its customers. In the end, Sikich discovered AltiGen, the leading provider of 100% Microsoft software-based Unified Communications solutions.

"Many businesses are coming to us today with rooms full of 'end of life' hardware with no support and no options," stated head of Sikich's Technology Service Area, Jeff Rudolph. "It doesn't make any sense to provide these companies with new proprietary hardware-based solutions subject to the same fate. We needed a real solution to address this ongoing problem. In addition, businesses today have gone mobile and we wanted a true mobility offering. Most importantly, we desired a solution that made sense In terms of our commitment to Microsoft technologies. After reviewing all of the telecom product options, we are pleased to offer AltiGen solutions to our customers."

"It became very clear that AltiGen was different from the rest in terms of their Microsoft UC offering," stated Sikich Partner, Dennis Suglich. "They don't just use Microsoft as a 'plug-in' or sales pitch. As a true Microsoft-based software solution, AltiGen is one of the few vendors certified for Microsoft OCS via the Microsoft Open Interoperability Program, with their native SIP integration to OCS. As a true open, standards based solution, combined with their Mobility and Microsoft story, AltiGen is truly in a category of their own."

"We are excited about adding Sikich to our growing reseller network," said AltiGen Director of Channel Development, Bill Glau. "With twelve service areas and dedicated industry teams, Sikich is now able to provide advanced Unified Communications solutions to their customers and continue to grow their already impressive footprint throughout the Midwest."
