RingCentral Expands Its Lawful Interception Capabilities with PertSol's iNterceptor Platform

/ overview /

Expanding Lawful Interception Across a Growing UCaaS Environment

RingCentral, a leading global Unified Communications as a Service (UCaaS) provider delivers cloud-based voice, messaging, and collaboration services to enterprises worldwide. As its regulated voice operations in India expanded beyond the initial site, the organization required a scalable approach to extend lawful interception coverage while maintaining centralized governance, compliance, and service continuity.

Challenges Driving Transformation

Scaling Beyond a Single Interception Site

As the provider expanded its regulated voice operations, lawful interception capabilities needed to extend beyond the initial deployment. New interception points had to operate under the same centralized controls for warrant handling, provisioning, monitoring, and audit management without creating operational silos.

Solution Strategy & Implementation

Passive Probe-Based Interception

PertSol deployed iNteliProbe at each interception point to capture mirrored VoIP traffic from 10G network streams. Its passive architecture enabled lawful interception without impacting live services or requiring network modifications.

Centralized LI Governance

Each interception point was integrated with the centralized iNterceptor Management System and Mediator, enabling unified warrant handling, target provisioning, monitoring, reporting, and audit control across all operational sites.

Real-Time VoIP Processing

The platform generated Intercept Related Information (IRI) from SIP signaling and reconstructed Call Content (CC) from RTP and SRTP streams, enabling accurate real-time interception of voice communications.

Compliance-Ready LEA Handover

The solution produced ETSI HI2/HI3-aligned outputs and enabled secure delivery of IRI and CC information to authorized agencies through approved workflows and handover mechanisms.

High Availability Architecture

Redundancy was implemented at each interception point to eliminate single points of failure and support uninterrupted 24×7 lawful interception operations across the distributed UCaaS environment.
