■ Time
This fields contains the time that the call ended, or the time that a user
dropped from a multiparty 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, Avaya MultiVantage
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.
■ Dial plan
If the dial plan supports 6/7 digit extensions, only the formats that already
support Calling Numbers longer than 7 digits (expanded, Unformatted,
customized, and international ISDN) support 6 or 7 digits. All other
formats send only 5 digits and when a 6 or 7 digit extension is involved, the
last 5 digits are sent.
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 Avaya MultiVantage 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.
