Asterisk cdr billing setup

I have cdr recording succesfully setup to plain csv as well as mysql. I have the Areski GUI running and can view all the calls and their details.

However I want to setup some costing for internal use and as a second record to verify bills from my termination provider (they are great and I trust them, but I just think it would be cool:P).

How would I go about this? Is it built into the dialplan or the cdr somehow?

Thanks

All of your calls are logged in the master csv file. To setup cost routing and billing I suggest looking into astcc. I hope this helps.

Where can I find master csv file?
Thank you.
