Key Mapping
There are hard keys on your phone, such as Hold, Redial, Xfer, and Conf that are
configured by default for specific call-handling features. (See the product-specific
User Guide for more information about these key functions.
Enabling/Disabling Redial, Xfer, and Conf Keys
You can enable or disable the Redial, Xfer, and Conf keys as required using the
following parameters in the configuration files:
• redial disabled
• conference disabled
• call transfer disabled
Valid values for this parameter are 0 (enabled) and 1 (disabled).
If this parameter is set to 1, the key is not active and is ignored if pressed by the
user. For "redial disabled" the value of 1 does not save the dialed number to the
"Redial List".
If this parameter is set to 0, the key is active and can be pressed by the user.
This feature is configurable via the configuration files only.
Notes:
1. On the 55i and 57i, the Xfer and Conf keys are hard-coded by
default on keys 5 and 6 to the left of the LCD display
and cannot be reassigned. The Xfer and Conf labels display
when you lift the handset. To disable these keys, see the next
paragraph.
2. On the 53i, the Xfer and Conf keys are assigned by default to keys
5 and 6, respectively. These keys are programmable keys and can
be reassigned if applicable. To disable these keys, see the
next paragraph.
