Automatic addition of dialing prefixes to outgoing calls!
IntlPrefix automatically adds dialing prefix to outgoing phone calls. This allows you to store all your phone numbers in international "+country-area-number" form, and IntlPrefix will automatically replace "+country" by the user-defined prefixes for domestic and international calls when calling.
IMPORTANT: if prefixing does not work, use the "Alternate conversion method" option (some handset models do not respect Android standard and need this option).
