Outbound Call being identified as connected or missed.

Currently there is now way to identify if outbound calls are connected to a customer or missed. And since the call length of some calls that are going to voicemail are over 1 minute, it is impossible to filter out all outbound calls that go to voicemail. If there was a signifier such as the missed/answered identifier on inbound calls, it would be very helpful analytical purposes instead of guessing if a short call was connected or went to voicemail.
