Message Notification to Normal Telephone Numbers
Below is a basic overview of how Message Notification works with phone numbers assuming the retry
attempts are at default. The system determines which numbers are internal extensions or external
numbers by the system dial plan settings. Depending on the system, ARS routing maybe needed to
properly route external calls.
1.
The subscriber activates Message Notification for their mailbox.
2. When the subscriber receives a new message, the InMail dials the first active destination in the
cascade that should receive the Message Notification.
• InMail waits up to 30 seconds (approximately five rings) for ringback, reorder, busy or voice
activity from the called number. If nothing is detected, the callout is considered unanswered
(RNA).
3. If the recipient answers, InMail plays the notification message (“Hello, I have a message for”) and
asks the recipient to dial 1 to log onto their mailbox. The recipient hears the notification message
if:
• They say “Hello” after answering the callout, or
• The system receives answer supervision from the Telco after the recipient answers the call.
(Note that the recipient can skip the announcement by dialing 1 to log onto their mailbox after
answering the callout – without saying “Hello”.), or
• The notification is to a system extension.
4. Once the recipient logs onto the mailbox, the notification is considered acknowledged and will not
reoccur until the subscriber receives new messages.
