Cdr problem

Hi all,

I’m dealing with CDR.

What i need to do is to let a specific international prefix (0039) appear for all the national, toll free, an some other special number in my country (for billing purpose, unfortunatly its a customized software not really standard but i cannot
put words on it.

From the dial rule point of view, no problem. I user the dial rules in the trunks to do this settings and all work fine for me. But unfortunatly the prepend prefix and logic i used in these dial rules don’t appear in the CDR of Freepbx.

Any suggestion?
Should i create something custom to fix this?
