Use the Key Mapping tab on the auto attendant's Property sheet to define the telephone keys that callers can press when they reach the Unified Messaging (UM) auto attendant. You can define separate key mappings for business hours and non-business hours. A key mapping is defined as an entry in a table that has as many as nine entries. The 0 (zero) key is reserved for a transfer to the operator.

For example, a key mapping that is used during business hours may enable a call transfer to another extension where a human operator or receptionist is available. For non-business hours, the option to transfer to another extension may not be available, or the call may be forwarded to a UM-enabled mailbox so the caller can leave a voice message.
