Features and technical reference
1267Call Detail Recording
20
■ Time
This fields contains the time that the call ended, or the time that a user
dropped from a multi-party call, if Call Splitting is active.
■ VDN (vdn) — 5 digits
This field is only available on customized records. The call record contains
the VDN extension number. If VDN Return Destination is active, this field
contains the first VDN the caller accessed.
Security
Monitor call detail records daily for unusual calling patterns, long calls,
international calls, calls outside of normal business hours, and other indications of
toll fraud. Call accounting systems are available that automatically monitor CDR
output for fraudulent calling patterns.
Considerations
■ Date and Time
If a time of day is not administered in the system, DEFINITY ECS does not
generate CDR records. If the time is changed while a call is in progress, the
actual duration for that call is not reflected in the CDR record. Instead, a
special sequence of 9999 is recorded in the CDR record to indicate that the
call was in progress during a time change.
Interactions
■ Abbreviated Dialing
When a user places a call using Abbreviated Dialing or a Facility Busy
Indicator button, all outpulsed digits appear on the record.
■ Answer Detection
The DEFINITY ECS provides Answer Detection using a Call Classifier
circuit pack. This feature is an option for your system and requires an
8-port call classifier circuit pack. CDR starts recording call duration at the
time the answer is detected by the circuit pack.
■ Attendant Console
If an attendant-assisted call involves an outgoing trunk, the primary
extension of the user who requests attendant service is recorded as the
calling number, even if the attendant dialed the outside number. Condition
Code 1 indicates the call was assisted by the attendant.
