Metaswitch Networks Expands Leadership Team

Key Management Additions Support Accelerated Growth and Market Development

Alameda, Calif.: October 8, 2009 — Metaswitch Networks, a leading provider of carrier systems and communications software solutions, today announced the appointment of two industry veterans to its leadership team. Stefan Knight has been named to the newly-created post of vice president of strategic alliances and Steve Gleave will lead as vice president of marketing, both in the company's Carrier Systems Division. With the appointments of Knight and Gleave, Metaswitch Networks underscores its accelerated growth path and strengthens the ongoing global market development capabilities of its carrier systems business.

Stefan Knight is responsible for developing new alliances and maintaining partnerships that will deliver ongoing innovation, multi-vendor solutions, and long-term value for customers. Knight brings 18 years of experience, most recently at Ericsson, driving product requirements and commercial strategies for telecom equipment manufacturers. Prior to Ericsson, Knight led product management, marketing and business development teams at Virata, CopperCom and Entrisphere.

Steve Gleave has assumed the principal marketing role for the Carrier Systems Division and will bring greater focus on driving continued expansion of the complete portfolio of Metaswitch solutions. Gleave brings more than 20 years of marketing experience working with high-growth companies in the network technology sector, including senior marketing roles at Endace, SS8 Networks, Ubiquity Software and Jetstream Communications.

Andrew Randall, who previously held the role now occupied by Gleave, continues as a key member of the executive team, moving into a corporate-level position as senior vice president for marketing and business development. Speaking of the appointments, Randall said: "We are tremendously excited to be bringing this exceptional talent into our executive team. Together, Steve and Stefan will enable us to build more strategic relationships with partners and customers, and grow our business in new markets."

"Metaswitch has, with little fanfare, built a position as a worldwide leader in carrier VoIP solutions over the last 9 years, based on its demonstrated commitment to engineering quality, reliability, exceptional support and innovation," said Gleave. "It is my job to get word out about that success, accelerate the company's growth and ultimately enable the creation of the industry's next major global player."
