Voice Logger

HI,
I have asterisk based voice logger that we use with PRI cards, i can listen to calls with browsing them and use also, but some of users need easy application than using linux so that they can see call going on if they want they can hear running call , and they can delete particular calls if they want and think that work is finish on particular call. ?

Is there any open source software for that ?

Please help !
