Can I get calls missed while busy (on another call) to show in call history?

[AC Question]

Can I get calls missed while busy (on another call) to show i call history?

Currently my call history shows calls out, answered and missed. But the missed only shows if the phone rings and i don't answer. if the call is missed because i'm on another call then it doesn't show as a missed call in my history. It gets annoying because sometimes my voicemail 'forgets' to send a text saying a new voicemail has been left. Any held would be appreciated.
