Do not re-download Net2Phone, simply double click on the previously downloaded exe. If your microphone and speakers are built into your monitor, we suggest that you use a headset with microphone. Set both microphone and speaker volume as low as possible, just enough to have a normal conversation. Adjust the playback and recording control to the lowest comfortable level. Click on the MUTE button when you're not talking during the call and release it when you start talking.
Place calls during low Internet traffic times.
Since your voice is carried in packets over the Internet, high Internet traffic may cause packet loss, which degrades the quality of the call and may cause an echo. To determine the best time to call, consult your Internet Service Provider. Lastly, if you're the one hearing the echo, you might be having a problem with your multimedia device properties. Click on the Speaker icon in your system tray on the bottom right corner of your monitor and raise the volume bar to the top. Make sure 'Mute' is not checked.
