If you make active use of your Internet connection in addition to telephony, overloading can lead to poor voice quality during a telephone call.
In order to make calls with the best quality at all times, we recommend that you configure a bandwidth management system. A telephone call requires a bandwidth of 100 kbps (upload and download). Please note that a good call quality is often directly related to the correct settings.
We would be happy to advise you. Don't hesitate to contact us if you need any assistance.
