Samsung SCH-U740 Alias

i noticed today while on a phone call, on the front screen on the bottom right corner is an 'options' choice. i clicked it & noticed the option for voice record. i clicked it, it appeared to be recording the call but once you get out of it, where do you go to hear the voice record? is this feature actually recording a call or whats it about? can someone please tell where do i find the recorded info on this phone? thanks.
