Configuration Dialog: [Options > Audio]
The settings of this audio-dialog are stored and will be automatically re-activated with phone calls. The last set audio settings are stored and re-activated with end of conversation (slow cross-fade). Adjust Microphone Volume You set the local microphone volume by the upper slider. Adjust Speaker Volume You set the volume of the local playback over headphones or loudspeaker by the lower slider. Testing Audio Settings To the test the audio settings click onto the audio-test button. Now your microphone is connected with the speaker, so you will hear yourself. You should set the microphone volume on approximate 50 % and adapt the speaker volume after that. Minimise Echo Echoes arise through audible back coupling of the loudspeaker onto the microphone at the respective interlocutor. Therefore you hear yourself with a small delay since the microphone of your interlocutor sends a mixture of his own voice and your loudspeaker voice onto you. The same one is valid for your interlocutor in reverse direction. You should attempt on every case to minimize the back coupling for your interlocutor: You should use a headset, that an audible decoupling as good as possible has between microphone and the headset loudspeaker, for example the USB headset "DSP 100" from Plantronics. The sensitiveness of the microphone should be as low as possible. The conversation user should be able to hear you, however, still clearly. The playback volume should also be minimized. ISDN speech recording The ISDN voice recording is only then possible if you phone about headset (sound-card) and ISDN-card. In this case the voice dates are processed by the CTI Client and can also be recorded. If you phone with a normal telephone, no voice recording is possible.
