Introduction
The Nortel Networks Business Communications Manager Call Detail Recording is an application
that records and reports call activity. Each time a telephone call is made to or from your company,
you can record the information about the call. When the call is completed, you can print
information about the call in a report. Call Detail Recording also provides information on
incoming calls as the events occur. This information appears in a Real Time Call record.
