•
An external trunk call reaches an unanswered extension and the call is forwarded to voice mail
(
pattern trunk-to-ext no-answer
command).
Prerequisites
•
FXO hairpin-forwarded calls to voice-mail systems must have disconnect supervision from the
central office. For further information, see the
FXO Answer and Disconnect Supervision
document
.
•
To configure patterns that your voice-mail system will interpret correctly, you must know how the
system routes voice-mail calls and interprets DTMF tones (see the
“Call Routing Instructions Using
DTMF Digit Patterns” section on page 243
).
You can find information about how Cisco Unity handles voice-mail calls in the
How to Transfer a
Caller Directly into a Cisco Unity Mailbox
document. Additional call-handling information can be
found in the “Subscriber and Operator Orientation” chapters of any
Cisco Unity system
administration guide
.
For other voice-mail systems, see the analog voice mail integration configuration guide or
information about the system’s call handling.
