Customer backlash from blocked legitimate calls and unresolved fraud charges

3 verified sources

Definition

Over‑aggressive or poorly tuned fraud detection often blocks legitimate high‑volume or international traffic, creating service disruptions for enterprises and high‑value users; conversely, under‑detection leaves customers facing unexpected international or premium‑rate charges they must dispute. Both lead to complaints, churn, and pressure for credits.

Key Findings

  • Financial Impact: Carriers report that false positives in fraud systems cause lost usage revenue from blocked calls and contribute to higher churn; for large B2B segments, losing even a few enterprise accounts due to repeated blocking or unresolved fraud billing can cost millions in annual contract value.
  • Frequency: Daily
  • Root Cause: Static thresholds and simple rules do not account for customer context, so legitimate surges (marketing campaigns, seasonal peaks, rapid growth) resemble traffic pumping to basic systems; on the other side, insufficient controls on known fraud vectors like Wangiri and IRSF lead to repeated consumer bill‑shock experiences.

Related Business Risks

Artificial traffic pumping and IRSF driving uncollectible wholesale and retail charges

Global telecom fraud losses (dominated by IRSF, Wangiri and related artificial traffic schemes) are consistently estimated around $28–40 billion per year, with IRSF alone historically accounting for several billion annually; individual operators report single incidents in the $100,000–$1,000,000+ range when traffic pumping runs unchecked for a weekend.

Escalating fraud management and dispute handling costs from inefficient detection

Industry research and vendors note that manual fraud operations and reactive investigations can consume several percent of a carrier’s fraud‑related OPEX, with large operators running 24/7 fraud teams and paying six‑ to seven‑figure annual fees for outsourced monitoring and tools; these costs scale with fraud attempts even when no revenue is recovered.

False answer and call quality scams generating refunds and SLA penalties

In affected routes, a material share of minutes (TransNexus cites high answer seizure ratios with very short calls as key indicators) can be falsely billed, forcing operators to credit customers or absorb losses on disputed wholesale invoices; for major carriers, this can scale to hundreds of thousands of dollars per route per year.

Delayed fraud recognition leading to late billing disputes and slow recoveries

While exact figures vary, industry reports highlight that delayed fraud detection in roaming and international traffic can add weeks to collections cycles for large disputed invoices, commonly in the hundreds of thousands of dollars for a single event, effectively extending time‑to‑cash for a portion of high‑margin traffic.

Network and trunk capacity consumed by artificial pumped traffic

Vendors report that fraud systems must monitor five‑minute samples for suspicious spikes because pumped traffic can rapidly consume available capacity; for operators with constrained international gateways, lost legitimate traffic during attacks represents foregone revenue that can easily exceed tens of thousands of dollars per major incident.

Regulatory exposure from inadequate fraud controls and inaccurate billing

Regulators in many jurisdictions have forced operators to reimburse customers for fraudulent or artificially inflated charges and in some cases levied fines for mis‑billing and failure to protect consumers; depending on the market, these can range from hundreds of thousands to multi‑million‑dollar exposures over repeated incidents.
