Ok guys I know there is a lot of computer wizards out there. Please help,... I used to work on trackphone...?

They had this cool program. Trackphone is a call center so the program records everything that the customer service representative does in his/her computer. But he/she is not aware of this, does some one know what the name of this program is? or can someone provide the name of a program that does the same thing. It doent matter if its freeware or not. Please ist. The floor has about 300 agents and we want to record what each agent do on computer. thanx!!!. please answer.
