Carrier code in wrong location
 

I am attempting to use outlook to call my contacts.
I can do it for local calls, however I have to input a long distance
pin (carrier code) when dialing out.
However the format which I have to dial is: 8 (###) ###-#### %%%%%%
where # is the 10 digit phone number and % is my long distance code.
Outlook by default places the carrier code before the 10 digit number.
Is there any way to change the order in which the carrier code is
dialed?
