Solution Strategy & Implementation

Probe-Based Traffic Capture

PertSol deployed iNteliProbe at interception points to capture mirrored SBC traffic through optical taps and traffic mirroring. This passive architecture enabled lawful interception without impacting production voice services.

Centralized Interception Management

The iNterceptor Management System provided centralized warrant lifecycle management, target provisioning, audit logging, monitoring, and role-based access control across the distributed deployment.

ETSI-Aligned Interception Processing

The platform generated Intercept Related Information (IRI) from SIP signaling and reconstructed Call Content (CC) from RTP and SRTP streams, enabling standards-aligned lawful interception workflows.

Secure LEA Handover

The iNterceptor Mediator aggregated and correlated intercepted information while supporting secure delivery of HI2 and HI3 outputs to authorized agencies through controlled workflows.

High-Availability Compliance Architecture

The deployment incorporated redundancy across management, mediation, and delivery components while supporting system upgrades, validation, and vulnerability assessments to ensure long-term operational stability.
