Listen to remote Mic, Speaker ( headphone ) on LAN. mic use

Hello! I need a small desktop software to listen to remote Microphone / Speakers to listen to both sides on Skype. I will listen this on my local area network only. ( not on internet ) . I just need to watch my employees what they speak to my clients. You can make it in any language. i need both server and client side applications. Client application must be password protected. Below is the explaination on how to make the Server side application: A control panel screen , where i will add some IP addresses of LAN ( local area network machines ) , The Server application will automatically check all machines each 5 seconds or 10 seconds to make sure the employee is online or not. if machine is online, i can click on "Listen" button to listen to both Microphone and Speakers ( employee and client ) on that machine. There should be an option to stop the microphone on LAN machine ( the employee ) , and i speak instead of employee to the client from my own machine. it is like i sit on my machine, use your software to stop the remote mic on LAN and i speak to client instead while i am sitting on my server machine. in this case, the employee will see "WAIT" message on his screen. so he understands that i am speaking to client directly. Both client side, Server side applications must be Virus, Spyware Free! it should not be a virus. both server and client applications will be visible. if on any step i got antivirus notification or if i found any other threat , i will open a dispute against this application on freelancer.com Thanks for the co operate.
