unique detail of information

Dear Team,
My system:
VERSION: 2.6-372a
BUILD: 120713-2123
© 2012 ViciDial Group
I want to have unique call record in vicidial for comments filed for each call for each number.
since because by default it is updating in vicidial_list table for each call and each number.
so finding out the detail for each call is difficulty
so help me with that.
