Access Stimulation / Traffic Pumping

Also known as: Access Stimulation

Traffic pumping (access stimulation) is a fraud in which a small local exchange carrier partners with a high-volume service (chat lines, conference bridges) to attract inbound long-distance calls, then bills long-distance carriers inflated access charges for terminating that traffic. In mobile and SMS contexts, the equivalent is inflating A2P or voice traffic to specific ranges to maximise termination or share revenue.

Traffic Pumping in context

Telecom fraud costs operators an estimated $40+ billion per year. Common vectors include International Revenue Share Fraud (IRSF), Wangiri callback scams, SIM box bypass, PBX hacking, subscription fraud and A2P grey routing. Effective defense combines real-time signaling analytics with CDR-side machine learning.

Telecom networks depend on Internet-style routing (BGP, DNS, MPLS) for interconnect, transport and application delivery. Route hijacks and DNS abuse can degrade or intercept signaling as easily as any application-layer attack, which is why RPKI and DNSSEC are now standard hardening for carrier networks.

To place Traffic Pumping in the wider telecom-security picture, review Toll Fraud, OTT Bypass, SIM Box, Refile, AIT and BGCF.
