BB Curve 8500 :: Smart Dialing For International Calls

I m from Brazil and I have just changed my device from the 8300 series to the 8500 series. All the contacts in my outlook have the phone numbers in the following format + (country code) - (area code) - xxxx-xxxx. I cannot dial in my new device because I have not been able to set up the dialing mode to automatically recognize this dialing format. Where can I do it? I used to have it in my 8300 series device, but I forgot how to do it.
