Free Nokia C7 program recorder download.

Hi Guys! I own a Nokia C7 which I use for official assignments. There are times when it is necessary to record phone conversations to ensure quality of services and to provide reference in terms of service to our clients. I need a Nokia C7 program recorder download that I can use to accomplish this task. It is not for any spy jobs or blackmail. If you have personally used the application, kindly provide more insight on how it works and possible versions and or options.
