It could just be me, but the world is full of acronyms especially TLA's. What is CDR? Not the code, the acronym.
Heh... sorry Lynn... you're right about that...
CDR = Call Detail Record. Each record contains all of the information for a given phone call... whether it was actually connected, what the duration was, calling number, called number, account # of the caller (or the person called if 800 or reversed charges), type of call, time of day, "time band", etc, etc. Includes country and city code in the phone number if call was placed outside of NANPA (North American Numbering Plan Association). For several countries, like Mexico, contains "Band" information, etc. They may also contain provider information (which company originated the call), cost information, tax info, and a wealth of other information.
Each company seems to have it's own idea of what should be on a CDR even though there is a standard (EMI - Electronic Message Information) that most folks use to bill the calls to customers through 3rd party companies like ZPDI (I have no idea what that company acronym stands for).
