Optimize audio

Configure your PPG for the best audio quality

For the best audio quality when using a router you should set up your Router and PPG application to use NetMeeting mode.

Overview

There are two modes of operation for the PPG software;

1.	Tunnel mode, tunnel mode is easy to configure and will work with almost any router but the audio quality is not as good as NetMeeting mode.
2.	NetMeeting mode, NetMeeting mode will give you better audio quality but needs a router that supports NetMeeting mode.

If both your PPG and your USB Phone are connected to internet directly (not behind a router), the PPG application and the IP Phone center will automatically be set as NetMeeting mode and the audio quality should be optimized.

If either your PPG or USB Phone are connected to internet via a router, PPG and IP Phone center will automatically be set as tunneling mode and there will be some degradation of audio quality.
