Visto Expands its ConstantSync Platform to Offer Visto Mobile Secure Voice

New Voice Capability Delivers More Choice and Greater Flexibility for Mobile Email Users On the Go

REDWOOD CITY, Calif. – October 11, 2005 – Visto Corporation, a leading global provider of secure push mobile email, today announced that it will expand its existing voice capabilities to offer Visto Mobile Secure Voice™, a groundbreaking new feature that enables mobile professionals on the go, for the first time, to respond to emails using voice. This new capability is a result of the acquisition of Trekmail, the leading provider of mixed-media messaging services.

“As mobile email moves from a niche solution to a mass market necessity, mobile professionals from small offices and larger organizations will seek messaging solutions that provide them with more choice when it comes to handsets and email server support, and more flexibility when it comes to handling critical business communications,” said Nicholas McQuire, senior analyst at the Yankee Group. “By incorporating a secure voice option into a mobile email platform, business users have access to a wider set of response options, further enhancing the productivity benefits of mobile email.”

By integrating this new technology into Visto’s ConstantSync™ platform, a powerful push-based architecture, Visto is transforming the way enterprises and mobile professionals respond to and send email. With the click of a button, mobile workers can use voice to compose or respond to an email, making it easy for today’s harried professional to keep on top of emails when out of the office and on the move. And, for those users without keyboards on their mobile devices, this new technology obviates the need to thumb through numeric keypads to construct simple email messages. Visto Mobile Secure Voice also integrates into both the wireless operator’s and the enterprises’ voice mail systems, providing mobile professionals from businesses of all sizes with a lifeline to critical business calls when away from the office.

“Email is like oxygen in a business environment – it is a basic necessity for sustaining communication and enhancing productivity,” said Brian Bogosian, chairman, president and CEO of Visto Corporation. “Voice is the next logical step in the progression of mobile email, providing mobile professionals with the freedom to choose how to communicate, depending on the situation and the business need. We will continue to lead this market - in terms of handset support, customer traction and most importantly, through innovation. By continuing to expand our platform to offer mobile users more choice and flexibility, we empower the wireless operator to drive mass enterprise adoption of mobile email.”
