Show dial/call duration
If i understood you correctly, you want to get notified when a call goes through, not when the other person picks up? You could try Settings -> Call settings -> All calls -> Call status tones -> Call connect tone to get a sound from the speaker when the call connects, so you don't have to hold the phone to your ear. Is this what you were looking for?

Edit: I know, it doesn't answer the title but could help with the problem.
