SBX IP 320 Phone User Guide
Fixed, Pre-programmed, & Flex Buttons
The phone described in this guide has both Fixed, Pre-programmed
(sometimes also known as Feature), and Flex buttons. These buttons are used
to access and perform various tasks and functions. Some may be used in
conjunction with other buttons.
• Fixed buttons are those that are permanently labeled on the phone
hardware. Such buttons might include SPEAKER, TRANS, HOLD, VOLUME,
etc.
• Pre-programmed buttons are those buttons that are pre-programmed by
your System Administrator. Their names/functions will be on a more
temporary-type template that can be replaced if/when the buttons are
reprogrammed, etc.
• Flex buttons are also known as "User Programmable" buttons (see
“Programming Flex Buttons” on page 2-30). In addition, Flex buttons that
are programmed to access the dial tone, are also known as "line buttons".
