The "CDRe" feature broadens the scope of call data recording and generates not only call detail records but also, and more importantly, call data records. These call data records are transferred for further processing.

The goal of this feature is to cover as many CDRe changes as possible on the basis of the extended variety of requirements in OpenScape 4000. Because of their complexity, however, CDRe Traffic, CDR Account Code, and Elapsed Time Display are handled separately.
