Missed call notification Details 
Control incoming call notifications, so you can return every missed call. To receive notifications for missed calls only:
1) Select Send Notification on Every Call from the pull-down menu.
2) Check the boxes marked Unless the caller leaves a voicemail and Unless I’ve answered the call.
You can also configure your system to forward notifications for any combination of voice messages, fax messages, answered calls, or even all calls.
