Callers interact with the voice messaging system by using the keypads on
their touch-tone phones. The keypad map determines how digits are
mapped to letters.
Each digit on a caller’s phone is mapped to two or three letters in the voice
messaging system. Callers can enter a wildcard digit in place of any letter
when they are not sure of the letter. For example, a system using the Q=7,
Z=9 keypad map, the digits 7-1-1 represent P, Q, R, or S followed by any
two letters.
The voice messaging system supports five keypad maps:
The mapping of digits to letters should match the phone system and the
phones of the outside callers. The system uses the Q=7, Z=9 keypad map
by default. If your system requires a different keypad map, use the following
procedure to change it.
