The Authentication Code feature of CDR2Cloud provides a very accurate and flexible way for you to identify which customer each call in your CDR file should be billed to.
Every record (line) in your CDR file represents a call that was made through your network by a customer. In processing your CDR file you are now trying to review each record (line) and figure out:
Which customer made the call
How much to charge for the call
The Authentication Code feature gives you the resources you will need to accurately take care of 1. - Which customer made the call.
