The call accounting system that you use might be sold by Avaya, or it might come from a different vendor. You need to know how your call accounting system is set up, what type of call accounting system or call detail recording unit you are using, and how it is connected to the server running Communication Manager. You also need to know the format of record that your call accounting system requires.
Caution:
When migrating a platform from a legacy system to a Linux-based system of Communication Manager 3.0 or newer, where both the old and new systems use CDR, ensure that the older CDR parsing scripts correctly use all of the characters identified in each of the fields contained in the applicable format table (see the Format Tables in the Avaya Aura® Communication Manager Feature Description and Implementation).
