You have two options:

1) Use the CALLINGTON variable in the dialplan. This is only for the 
   calling party number, not the called party number.

2) Use the internationalprefix, nationalprefix, localprefix etc settings 
   in the zapata.conf file. I _think_ this will affect both the 
   interpretation of calling and called party and possibly also the 
   TON of the called number for outgoing links. I am nut sure under 
   which circumstances these variables are applied.

Isdn handling in Asterisk tends to be these kinds of hacks.
