If your call is disconnected for any reason, Skype will automatically attempt to reconnect your call.
                    
Skype will attempt to reconnect the call for 60 seconds. If it cannot establish a connection in this time, Skype will end the call.
If Skype cannot reconnect your call, make sure that:
    - You still have an internet connection.
- You have the minimum 
                        bandwidth required to make a call.
- You have closed any applications that use the internet (especially those that might be playing music or video) and cancelled any file downloads.
- You are using the latest version 
                        of Skype. If you’re not sure what version of Skype you 
                        are using, it’s easy to find 
                        out.
- If you are calling a landline or mobile, you have enough 
                        Skype Credit or a 
                        subscription to make the 
                        call. Get more

If you are making a Skype-to-Skype call, the person you are calling should also make sure of the above.
