US-based Sun Microsystems today announced the roll out of a regional telecoverage model aimed at helping the company reach high growth small-to-medium size businesses, startups and Web 2.0 companies in emerging economies. The 'Telecoverage' model involves Sun's centrally based call centre agents making contact with existing as well as potential customers to access and sell Sun's solutions. The telecoverage model will go live across the EM and Middle East region and will be implemented by local companies that Sun has partnered with in these markets.
