IP Office Programmable Buttons
As well as the usual dialing keys, Avaya digital and IP telephones have dedicated function buttons such as Mute, Volume, Hold, Conference and Transfer. In addition to these, on many Avaya digital and IP telephones there are keys that can be programmed with a range of selected special functions. These keys can be used for calling other extensions on the system (Direct Station Select or DSS keys), or can be used for options from speed dialing numbers to controlling features such as Do Not Disturb.
Many features use an indicator to show whether a feature is enabled. Button programming is done through the IP Office Manager as part of the system configuration, although some telephones allow the user to program buttons and functions where given administration rights.
