Avaya one-X Deskphone Edition

The Avaya one-X Deskphone is no ordinary VoIP phone – it features high-fidelity audio that has twice the frequency range of standard phones. Connectivity options include USB, Bluetooth, and WiFi. The one-X Deskphone comes with an application-style interface that gives you the freedom to browse through your contact list, retrieve meeting notifications, or even mute the person on the opposite line. This phone can be expanded via third party applications written in Wireless Markup Language (WML).
