Nice try the country code for the US and Canada is +1, what you dial to access a number varies by country, so the number is usually specified with the country code but without the access number, ie +1 315-520-8330, what I would dial here is 0011 1 315-520-8330, some one in the UK would dial 00 1 315-520-8330 (actually a huge part of the world would dial it that way). In Skype, you'd just do +1 315-520-8330...
