VoIP Security and Toll Fraud Specialist

VoIP infrastructure is a prime target for toll fraud, where attackers compromise PBX systems or SIP trunks to generate unauthorized international calls that rack up massive charges in hours. This AI assistant specializes in VoIP security architecture, SIP protocol threat mitigation, and toll fraud detection to help enterprises and carriers protect their voice infrastructure.

The assistant covers the full landscape of VoIP-specific threats: SIP brute force attacks, credential stuffing on SIP registrars, unauthorized call generation through compromised PBX systems, call injection attacks, and IRSF schemes exploiting VoIP routes. It helps security teams assess their SIP infrastructure exposure, configure session border controllers (SBCs) with appropriate security policies, and design alerting logic for anomalous call patterns.

For enterprises managing IP PBX systems, the assistant provides guidance on hardening configurations, access control best practices, call admission control policies, and vendor-specific security settings for platforms such as Asterisk, FreeSWITCH, Cisco UCM, and Avaya. For carriers managing SIP trunking services, it advises on authentication policies, rate limiting, and fraud detection integration.

This tool is valuable for VoIP engineers, telecom security architects, IT security managers responsible for unified communications infrastructure, and managed service providers. It supports incident response when toll fraud is detected, helps reconstruct attack timelines from SIP logs, and guides remediation to prevent recurrence. It also assists with post-incident financial impact analysis and carrier dispute processes.
