Hi I am having trouble using facetime to a friend in europe. I am in Canada. Do I include all the country codes, or do i just use their number and that is all?

I am having a difficult time using facetime to call a friend in Europe I am calling from Canada Her phone number in France is 0607------

If I were to call using a regular phone call it would be 01133607------ (notice the 0 is left out in front of the 6)

Which do I use? This latter one is not working. please help

We both have wifi, and when she calls me it works but when I call her even through the phone icon and not contacts, it does not work. I have used facetime to call Canadian friends in France with no problems. I think I have the number wrong some how.

Thanks for your time
