Distinguishing between placed received and non-received calls

On my Android phone, under the list of all phone calls, there are several distinct icons to distinguish between: - outgoing calls (a green arrow pointing away from the phone) - missed calls (a red arrow bouncing off the phone) - received calls (a blue arrow pointing into the phone) However, the user interface does not distinguish between placed calls which were answered on the other end and calls which were not answered on the other end. Does anyone have a user interface which distinguishes between these two scenarios or does anyone know of an upgrade I may perform in the user interface (perhaps even by going as far as installing CyanogenMod) so as to account for this difference in the user interface? I am running Android 2.3.4 (GingerBread) on an LG Optimus Net P690.
