9620L, 9620C IP Telephones  

Avaya 9620 IP Telephones are specifically designed for the everyday telephone user – those who typically rely on multiple communications tools such as e-mail and instant messaging (IM), yet still require a high quality and intuitive telephone for voice communications.

The Avaya one-X Deskphone family features an intuitive user interface which helps to make users proficient and confident in performing common telephone tasks such as setting up a conference call or completing a transfer.

With access to up to 12 lines and features through a simple-to-navigate interface, plus a clear view of 3 lines/features with LED indicators, the telephones are efficient to use while the small footprint consumes minimal space on a user's desktop.
