The notification list specifies who is a member of the On Call list. The Name lists the user/mailbox that will be used to store the recorded message.
The Notifications is a list of telephone numbers or e-mail addresses. One entry per line. Note that an e-mail notification will not cancel the notification schedule! Only a properly acknowledged call will cancel the schedule. The Notification Options specifies how the On Call user should be notified. Connect to Voicemail Box will simply deliver the message and cancel the notification schedule after the user has listened to the last new message. Notification with Confirmation will play back the Notification Prompt as specified in the On Call Box settings.
