Delta Career Education Corporation Grows With AltiGen's Advanced Call Center Suite

SAN JOSE, CA--(Marketwire - September 16, 2010) -  AltiGen® Communications, Inc. (OTCQX: ATGN) (PINKSHEETS: ATGN), the leading provider of integrated Microsoft-based Unified Communications solutions, helps Delta Career Education Corporation maintain fast-paced growth across the country.

Delta Career Education Corporation is an educational services company that operates for-profit, post secondary schools serving the growing need for career-oriented education in the new service economy. Delta's core mission is to provide educational programs that deliver real-life career skills and lead directly to employment upon graduation. Since 1998, Delta has provided education to over 16,000 students across 37 campuses through acquisitions and partnerships.

Delta's philosophy to provide individualized attention to each student throughout the education process requires a strong communications platform and in many cases advanced functionality to ensure students are always able to get connected. Delta realizes the value in finding one solution that meets all of their communications requirements for both existing and future campuses. Westel Communication Services, a premier AltiGen partner, has given them just that.

"AltiGen's Call Center capabilities far exceed any system we have encountered in our newly acquired schools," stated Bill Nance, Chief Information Officer. "From intuitive call center agent software to critical reporting and advanced call routing, we're happy with every aspect of the system. It's our goal to implement AltiGen's advanced software-based Call Center solution in every new campus. In addition, we are in the process of testing AltiGen's latest break-through mobility software -- MaxMobile. MaxMobile allows our management team to stay connected via smart phones giving us direct access to visual voicemail, employee directory with real-time presence, advanced call control and more -- anywhere in the world."

"Delta is a fast-growing company which we have supported for over five years," added Terry Winters, Chief Operating Officer of Westel Communication Services. "Our service, system implementations and proven reliability of the AltiGen solution has given us the opportunity to continue to support Delta. Recently we began work on a new Enterprise Licensee Agreement to support Delta's growth. The ELA program significantly reduces the complexity and costs associated with enterprise-wide VoIP deployments. In the future, Delta will have access to an unlimited number of applications, users and locations to accommodate expansion. We are excited to be a part of Delta's growth and successful education services."
