Ok, I am located in Toronto but using Dell Voice on my iPhone 4, I have an Edmonton number from Dell Voice that I can call to my friend in Edmonton who has a iPhone 3G. I call from Dell Voice to her traditional phone number from Fido. She's usually in the Edmonton area, specifically in West Edmonton Mall which is a great location for Dell Voice calling. However, every time I call her through Dell Voice, it gives me a message saying "Account Balance is Insuffient to Place your call to that Destination". From what I understand, you only pay for calls outside Canada and so I shouldn't get this message for account balances. Can someone please explain to me why I am getting this message? Really frustrating....

Someone please help.
