Two optional products, Avaya Cost Allocator and Call Accounting System (CAS)
Plus, enhance CDR/SMDR by allowing you to create customized reports. These
reports can be used to isolate calls that may be suspicious.
NOTE:
Only the last extension on the call is reported. Unauthorized users who are
aware of this procedure originate calls on one extension, then transfer to
another extension before terminating the call. Internal toll abusers may
transfer unauthorized calls to another extension before they disconnect so
that CDR does not track the originating station. If the transfer is to your voice
mail system, it could give a false indication that your voice mail system is the
source of the toll fraud.
Review CDR/SMDR records for the following symptoms of abuse:
■ Short holding times on one trunk group
■ Patterns of authorization code usage (same code used simultaneously or
high activity)
■ Calls to international locations not normal for your business
■ Calls to suspicious destinations
■ High numbers of “ineffective call attempts” indicating attempts at entering
invalid barrier codes or authorization codes
■ Numerous calls to the same number
■ Undefined account codes
For System 75, DEFINITY G1, and DEFINITY G3 and later:
■ To display the Features-Related System Parameters screen, use the
change system-parameters feature (G1 and System 75 only) or the
change-system parameters cdr feature (G3 and later).
■ Administer the appropriate format to collect the most information. The
format depends on the capabilities of your CDR analyzing/recording
device.
■ Use change trunk-group to display the Trunk Group screen.
■ Enter y in the SMDR/CDR Reports field.
For DEFINITY G2:
■ Use PROC275 WORD1 FIELD14 to turn on CDR for incoming calls.
■ Use PROC101 WORD1 FIELD8 to specify the trunk groups. Account code
entry can be required for CDR (see ‘‘Require account codes’’ on page 5-47
for details).
