Michael Curry, sales manager of AltiGen for Latin America, said: "General Motors (GM) was a perfect candidate for AltiGen's software-based call center. By deploying a solution that can be managed in-house and easily scale, GM was able to cost-effectively improve its operations and ability to service customers.

"AltiGen's Microsoft-based technology will also allow GM to integrate the call center with a planned Microsoft Exchange 2007 upgrade and take advantage of Microsoft's new unified communications functionality."

"General Motors was a perfect candidate for AltiGen's software-based call center," said AltiGen's Latin America Sales Manager Michael Curry. "By deploying a solution that can be managed in-house and easily scale, GM was able to cost-effectively improve its operations and ability to service customers. AltiGen's Microsoft-based technology will also allow GM to integrate the call center with a planned Microsoft Exchange 2007 upgrade and take advantage of Microsoft's new unified communications functionality."

The solution was implemented by iFone, AltiGen's call center partner in Mexico since 2003. "We support over 80 call centers and thousands of agents using AltiGen," said iFone Managing Director Antonio Trevino. "In our discussions with General Motors, we were tasked with creating an end-to-end solution that would improve their capabilities while cutting costs. Since opening this summer, the call center has expanded from 70 to nearly 100 agents. As the economy improves, we expect to continue to cost-effectively add additional agents and supervisors. As a solution provider, it is rewarding to help companies move forward despite a tough economy."

General Motors based its selection of AltiGen on the following key areas:

--  AltiGen's integrated application suite provides robust functionality
--  The software based solution can be easily managed in house
--  The product cost effectively scales on a per agent basis
--  AltiGen integrates with Microsoft Exchange 2007 and Microsoft Office
    Communications Server 2007
--  Product flexibility allows the call center to adapt real time to
    changing requirements

"Our call center is the centerpiece of our client support," said Romo. "We look forward to exploring more of AltiGen's capabilities and translating that to the benefit of our clients and distributors."
