I have IPCCX 4.0(5) installed and all services be enabled. I installed Cisco Supervisor Desktop and Cisco Agent Desktop. I can start recording in Supervisor Desktop when an agent receiving a call. I can see the recorded file in CSD > Recorded File. However, when I play this recorded file, or save it to a .wav file and plat it, I could not hear anything. Is there a settings somewhere that could fix this problem?
