No setup fee, only 0.03 USD for each resource per day.
            A resource can be:
            
                - Extension (local user)
 
                - External line
 
                - SIP trunk (SIP server)
 
                - Customized resource, such as audio files, IVR-XML, and so on
 
            
            For example, if you have three extensions and one external line, your account will be charged twelve ((3+1)*3=12) cents per day. 
            Please pay attention to following items. 
            
                - The virtual server will be charged on resources, not on how many calls you will make or receive.
 
                - If the account doesn't have any balance, you can still try calls, but the duration of each call will be limited to about 30 seconds.
