Avaya one-X Mobile, a software client that extends Avaya Inc. enterprise telephony to mobile employees, is now available for the Apple Inc. iPhone as a free download through the iTunes apps store, changing the way enterprises distribute applications to employees.

Avaya one-X Mobile provides integration with enterprise communications applications, including access to desktop extension features, visual voice mail, corporate directories, VIP lists, call logs and more. So with the one-X Mobile installed on their iPhones, calls made to employees’ desktop extensions are simultaneously bridged to their iPhones; likewise, outbound calls made via one-X Mobile for iPhone appear on caller ID as the employees’ enterprise extensions. Employees can switch between the iPhone and office extension without disrupting calls in progress.

End users will need an account on their company’s one-X Mobile application server, the URL for the application, user name and password, which are available through their IT department.
