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.
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.
Those programmable button not assigned as appearance buttons can be used for a range of other features. The features can be programmed by you or your system administrator. Note however that you may not be able to change the feature buttons set by your system administrator. 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.
The use of the button lamps depends on the feature associated with the button. Buttons programmed with a feature that is not supported by the phone display as "Invalid".
