The IP Office supports the 9508 telephone.

9400 Series and 9500 Series phones are physically identical. However, 9500 Series phones are only supported on IP Office systems whereas 9400 Series phones are supported on other Avaya telephone systems. This guide only covers use of phones on an IP Office system.

9508 annotated

This phone supports 24 programmable call appearance/feature buttons. The labels for these buttons are visible on the main display and can be controlled by the adjacent buttons.

Functions can be assigned to the phone's feature buttons by your system administrator or by yourself using self-administration. Note how you cannot replace features assigned to buttons by your system administrator but you can replace other features. Note also that there are features that the system administrator can assign that are not available for you to assign. This guide includes only the features that are available for you to assign if required.
