Avaya One-X Communicator


Avaya Softphone (aka “One-X”) is a software application that runs on your work computer and can augment your desktop phone or replace it completely. The software application is a great way to take your phone with you as you travel around campus. If you choose to run softphone it is recommended that you purchase a headset for use with softphone. Tested models can be found in the headset section below. Headsets must be purchased through your standard ordering channels.

One-X can be used alongside your desktop phone, accepting/making calls from either. Or you could choose to turn in your desktop phone and only use the One-X application.

As you use softphone, it is recommended that you use a wired data connected to your computer. Since Wi-Fi is a shared medium, you could experience degraded audio depending on proximity and number of other users sharing the Wi-Fi access point. Some types of network devices, such as firewalls, could impact usability of the Softphone service. Contact customer services for additional information.
