Windows users can install the Avaya one-X software; using the software requires VPN as well.

For macOS and all other non-Windows computers, or for anyone who does not want to use the VPN, the Avaya one-X software is also available via our Citrix server. You only need an Internet connection and a web browser to use this option.

To follow these steps, you will need to ask Telecom to enable your OSU extension for soft phone access. For more information, see Soft Phones - About.
