SIP & Network
The mean length of answered calls, used alongside ASR to distinguish genuine conversations from automated or fraudulent traffic.
Very short ACD — a handful of seconds — points to robocalls, wardialing, or Wangiri-style one-ring campaigns. Very long ACD to a narrow set of destinations can indicate traffic pumping or revenue-share abuse.
ACD is only meaningful compared against a baseline for the same customer, destination, and time of day.
ACD and ASR together separate a legitimate high-volume contact centre from an illegal dialer far more reliably than call volume alone.
The percentage of call attempts that are actually answered, used as both a route-quality measure and a fraud indicator.
A one-ring scam in which fraudsters place brief calls from premium international numbers so that curious victims call back at high cost.
Artificially inflating call volumes to a rural or high-cost destination so the terminating provider can collect inflated access charges.
The per-call record capturing calling and called numbers, timestamps, duration, route, disposition, and the customer responsible.
