                    If you are signed in to Skype but not making any calls, Skype will use on average 
                      0-4kbps. When you make a call, Skype will use on average 
                      between 24-128kbps. You can find out how 
                      much bandwidth a video call is using.
To find out if your internet connection is fast enough to make a Skype call:
                    
                      - In the Contacts list, select the contact you wish to 
                        call.
- In the call window, click the Check settings 
                        button. 
                         
 
- In the Connection tab, click Test 
                        Now. 
                         
 
- Skype will test the internet connection between you 
                        and your contact and display the results. 
                         
 
Audio calls should be possible with most internet connections. Video calls use a lot more bandwidth, so if you are having issues with the quality of your video calls, we recommend:
    - Closing other applications that use the internet, especially those playing music or video.
- Cancelling any file transfers in progress.
If this does not resolve your problem, you may need to increase your bandwidth. Contact your Internet Service Provider if you need more information regarding your download and upload speeds.
