FLASR1-LI-RTU Use Case
Real-Time VoIP Lawful Intercept for Tier-1 Telecom Operators
A global Tier-1 service provider deploys FLASR1-LI-RTU on Cisco ASR 1000 Series routers to intercept VoIP, IMS and SIP traffic at wire-speed. This solution delivers always-on lawful intercept streams to law enforcement systems via standard interfaces (H.248/MEGACO), ensuring zero packet loss, sub-millisecond latency and full compliance with ITU-T and ETSI mandates.
Multi-Jurisdiction Regulatory Compliance for National ISPs
A national Internet service provider integrates FLASR1-LI-RTU with its ASR 1000 edge-router farm to satisfy simultaneous intercept orders from multiple agencies. The RTU’s policy-driven filtering, secure data encapsulation (GTP/IPsec) and automated reporting reduce legal risk, accelerate audit readiness and ensure 100% adherence to local and cross-border lawful-intercept regulations.
Managed Security Service Provider’s Turnkey Intercept Offering
An MSSP leverages FLASR1-LI-RTU on customer-premises ASR 1000 devices to provide on-demand lawful intercept and network forensics as a service. Centralized RTU management via Cisco Prime and RESTful APIs enables rapid case provisioning, real-time data delivery and secure chain-of-custody, driving faster investigations and enhanced ROI for enterprise clients.
