Configuration Dialog:
[Options > Audio]


The audio settings are primarily required for the integrated SIP SoftPhone. For other TAPI devices, only the optional (parallel) call signaling is relevant under the [Extended Settings].


Adjust Volume

  • You set the local microphone volume by the upper slider.
  • 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
Echos are created by acoustic back coupling from the loudspeaker to the microphone at the respective call partner. Therefore you hear yourself with a small delay since the microphone of your call partner sends a mixture of his own voice and your loudspeaker voice onto you. The same applies to your call partner in the opposite direction.

You should attempt on every case to minimize the back coupling for your call partner:

  1. 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.
  2. The sensitiveness of the microphone should be as low as possible. The conversation user should be able to hear you, however, still clearly.
  3. The playback volume should also be minimized.

Extended Settings

Here you can make the following settings:

  • Ringer volume
  • Call signaling via second sound device (e.g. loudspeaker)
  • WAVE files for the ringtones
  • Special wireless headsets (see: integrated SIP SoftPhone)

Voice recording

Voice recording is only possible if you are using the integrated SIP SoftPhone. 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.
