in your Help Files, under "To Dial a phone number...", start with these instructions:

1. Enter phone numbers in this format: "+1-555-444-1212 ". This example will successfully trigger a skype call to a United States phone number.



then, add a check box "Don't ask me next time" to the confirmation dialogue box that appears before the call begins to dial, to make it faster.

Thank you for feature request, we'll consider adding this "Don't ask me next time" option.
