(CDW-G), the government and education subsidiary of CDW Corporation [Nasdaq: CDWC], today announced that Imran Abbas and David Lanexang, both solutions architects within the company's Technology Sales team, are certified Cisco Certified Internet Experts (CCIE), achieving the highest level of certification in the networking field. CDW Corporation recently achieved Premier Certification from Cisco Systems, Inc., having met stringent requirements related to technical training and customer support capabilities on Cisco products. The CCIE program trains technical experts with the skills and experience to handle today's most challenging technology assignments and sets the standard for internetworking expertise. "CDW-G provides added value to its customers through the ability to design and implement complex IT solutions from an in-house solution engineering staff," said Ken Grimsley, CDW-G vice president of strategic sales. "The combined experience and diverse technical expertise CDW-G maintains enables us to provide superior customer service and support to IT executives and their staffs." Mr. Lanexang and Mr. Abbas led and deployed 1,500 Cisco Internet Protocol (IP) phones for the Federal Trade Commission (FTC), enabling the agency to improve the capabilities of its phone systems and overall agency communications. By converting the FTC's PBX phone system to Cisco IP phones, the agency will be better able to expand and modify its existing system rather than switch to a new one to meet future growth requirements. The IP system also affords the FTC the flexibility to make system administrative changes easily due to its Web-enabled interface. A feature popular with IP phones is the unified messaging capability, allowing users to listen to their voicemail as well as their email, keeping them constantly connected. CDW-G's Technical Sales team specializes in security, wireless, and IP telephony solutions and provides IP telephony design and implementation, security solutions design and implementation, LAN/WAN design and implementation, onsite enterprise customer support, and pre-sales solutions consulting services.
