QoS stands for “Quality of Service”. Though the quality of your VoIP connection hugely depends on your VoIP service provider, but there are certain aspects that you may need to upgrade yourself to make voice sound clear and eliminate blutters and delays.

1. Upgrade your Internet connection. Download and upload bandwith is crucial for VoIP connection quality.

2. Use special software to optimize you computer performance through the broadband connection.

3. Upgrade your VoIP software. Codecs and technologies develop so fast, that every new generation provides better quality.

4. Check your headset. If it is of bad quality, this may be one of the reasons for VoIP problems.

5. Don’t download anything when calling. If your broadband line will be stuffed with data packages when you donload something, there can be too little capacity left for VoIP connection.

And don’t fret to complain to your VoIP provider. The level of rivalry in the segment is not big… it’s huge! So be sure your service provider will do everything possible to make things run smoothly for you.
