Our PSTN/ISDN to SIP Converter appliance bridges legacy circuit-switched networks (PSTN and ISDN) to modern SIP-based communications, enabling lawful interception of VoIP services in accordance with ETSI TS 102 232-5. This converter seamlessly transforms signaling and media streams from PSDN/ISDN networks into SIP, ensuring that voice and multimedia sessions can be captured by LI platforms. It allows operators and law enforcement agencies to continue intercepting calls when migrating from legacy infrastructure to IP-based voice systems.
PSTN/ISDN to SIP Converter
Our PSTN/ISDN to SIP Converter appliance bridges legacy circuit‑switched networks (PSTN and ISDN) to modern SIP‑based communications, enabling lawful interception of VoIP services in accordance with ETSI TS 102 232‑5. It transforms signaling and media streams from PSTN/ISDN into SIP so existing LI platforms can capture and process voice and multimedia sessions without major changes to your core systems.
Strategic Consulting
We help you plan and design the migration path from pure PSTN/ISDN environments to SIP‑based voice while maintaining continuous lawful interception capabilities. This includes interface definition, placement of the converter, and alignment with ETSI TS 102 232‑5 handover requirements.
Deployment & Integration
ICS supports you in deploying the converter into your live network, integrating it with existing mediation platforms and LI systems, and testing end‑to‑end call interception. Our team ensures that signaling, media and lawful interception data flow reliably through the new SIP‑based path.
Technology Solutions
Beyond the converter appliance itself, we offer complementary LI software and hardware solutions so you can build a complete interception chain from legacy TDM access to modern SIP handover interfaces. This creates a future‑proof environment where new services can be added without losing visibility or compliance.
