Segmental Insights

Voice-over-IP (VoIP)

What LI captures & where:
VoIP traffic (SIP/IMS/RTP, OTT voice) is intercepted at service/IMS layers and IP edges. ETSI’s IP-delivery handover (TS 102 232 series) defines how signalling (HI2) and content (HI3) are packaged and delivered to LEAs, including Service-Specific Details for messaging/IMS variants. Operators typically deploy mediation devices to normalize SIP headers, correlate call legs, and stream payload/metadata to LEAs.

Compliance & scope:
In the U.S., the FCC determined CALEA applies to interconnected VoIP and to facilities-based broadband providers, requiring intercept capabilities and compliance filings—cementing VoIP as a mandatory LI scope for carriers and VoIP providers.

Market impact:
VoIP’s session-rich metadata (caller/callee URIs, IPs/ports, call start/stop, codecs) increases mediation and DPI demand to reconcile distributed call flows (SBCs, NAT traversal, SRTP). Vendors that streamline ETSI HI2/HI3 delivery and lawful handover governance see sustained spend as voice continues shifting to IP/IMS.

 

Mobile Networks (2G/3G/4G/5G)

What LI captures & where:
3GPP defines LI architecture/functions across 2G–5G. In 5G SA, LI pivots to Service-Based Architecture with ADMF, LIPF, MDF and intercept points tied to AMF/SMF/UPF/NEF/PCF, plus IMS for voice. This moves LI closer to the user plane (UPF) and cloud-native cores, making orchestration and scaling central.

Compliance & scope:
3GPP/ETSI alignment standardizes handover into HI2/HI3 objects while accommodating roaming, mobility, and slicing. Operators must ensure selective, auditable delivery to LEAs across legacy/EPC and SA cores.

Market impact:
5G SA migrations trigger multi-year LI refresh cycles: new mediation at UPF, vLI (virtual LI) functions for NFV/SDN, and slice-aware warrant scoping. Spend concentrates on high-throughput capture, session correlation, and retention platforms that can sustain low-latency, high-volume traffic.

 

Next-Generation Networks (NGN)

What LI captures & where:
NGN consolidates voice/data/messaging onto IP and IMS, so LI hinges on standardized handover and service-specific details. ETSI ES 201 671 provides the generic Handover Interface (HI) model, while TS 102 232 parts formalize IP delivery and service-specific encodings—bridging heterogeneous NGN services to consistent LEA feeds.

Compliance & scope:
Because NGN spans multiple services/vendors, operators lean on mediation gateways that normalize protocols, map subscriber identities (IMSI/MSISDN/SIP URI), and enforce lawful filters.

Market impact:
NGN convergence expands LI integration scope: one mediation layer must handle voice, messaging, data, and OTT interconnects. This complexity drives demand for multi-service mediation, protocol translation, and policy-driven HI packaging, often delivered as modular platforms.

 

DSL & Cable Networks

What LI captures & where:
Broadband access providers implement LI at BNG/CMTS/edge routers and service cores, capturing IP flows and session events tied to subscriber lines. CableLabs PacketCable Electronic Surveillance and DOCSIS Broadband Intercept specs define how MSOs implement lawfully authorized surveillance, including interface points and Call-Identifying Information (CII) handover.

Compliance & scope:
FCC has clarified CALEA obligations for facilities-based broadband—so DSL and cable operators must support LI capabilities and auditable delivery, often via safe-harbor conformance to sector standards (e.g., PacketCable ES).

Market impact:
As fixed broadband remains a major origin/termination path for VoIP/OTT, operators invest in subscriber-aware mediation, IP session correlation behind NAT/CGNAT, and scalable retention—key growth vectors for LI appliances and services in the cable/DSL domain.

 

Wireless LAN (WLAN)

What LI captures & where:
WLAN is typically intercepted upstream by the access/service provider rather than at every Wi-Fi AP, using the generic ETSI handover model to deliver IP-level content and metadata correlated to subscriber identities, DHCP/AAA logs, and captive-portal records. The HI model (ES 201 671 → TS 102 232 family) remains the reference for packaging/delivery.

Constraints:
WLAN traffic is heavily encrypted (WPA2/3, TLS/HTTPS), reducing payload visibility and shifting emphasis to metadata, identifiers, and lawful selectors (MAC/IP/SSID/time/location). Mediation must de-duplicate and attribute sessions crossing Wi-Fi↔cellular↔fixed paths.

Market impact:
The ubiquity of Wi-Fi in enterprises and public venues elevates demand for metadata-centric LI, log correlation, and policy-driven selective handover, boosting spend on mediation platforms that can stitch WLAN events to ISP/operator identities under ETSI HI governance.

 

Why this matters for the LI market

Across all five domains, the through-line is standardized handover (ETSI ES 201 671 / TS 102 232, 3GPP LI) and jurisdictional mandates (e.g., CALEA). This drives sustained procurement of:

• Mediation & delivery layers that normalize multi-protocol traffic into HI2/HI3 objects.

• Packet/flow capture adjacent to SBCs, BNG/CMTS, and 5G UPF with lawful filtering/warrant scoping.

• Retention, audit, and compliance tooling that provides selective, auditable access across VoIP, mobile/5G, NGN, broadband, and WLAN footprints.

This segment represents deep, strategic engagement with interception platforms. Agencies like the NSA (U.S.), GCHQ (UK), and India’s RAW require:

• High-capacity systems for bulk data collection and filtering

• Deep integration with threat intelligence feeds

• Long-term data retention with AI-assisted searchability

“National security agencies are driving demand for interception that doesn’t just collect data—it analyzes context, relationships, and intent,” says a cybersecurity lead in a Southeast Asian intelligence bureau.

3. Telecom Operators & Internet Service Providers (ISPs)

Under regulatory pressure, telecom and internet providers must maintain intercept-ready infrastructure and often act as the first point of access for lawful interception commands.

Responsibilities include:

• Maintaining LI-compliant architecture (e.g., ETSI, CALEA)

• Coordinating data handover in real-time

• Ensuring zero impact on customer services during interception

ISPs and telecoms increasingly outsource interception platform integration to specialist vendors to ensure compliance while minimizing operational complexity.

Real-World Use Case: Integrated Interception in South Korea

A high-level cybercrime investigation unit in South Korea used a hybrid lawful interception platform to dismantle a cryptocurrency fraud ring in 2024. The suspects operated over VoIP calls, encrypted chat apps, and anonymous browsing networks.

The agency partnered with a local telecom provider and deployed a metadata-driven, cloud-interception gateway that monitored call records, browser fingerprints, and IP routing behavior . Within 48 hours, they identified the origin nodes and physical locations of the ringleaders.

• Outcome: 17 arrests, seizure of $5.2 million in assets, and exposure of an international laundering network.

• Technology Used: Cross-platform mediation, VoIP monitoring, encrypted traffic analysis, and AI-based communication clustering.

This scenario highlights how modern LI platforms can shift investigations from guesswork to precision-led, cross-border surveillance.

The role of end users is evolving from data collectors to intelligence architects, requiring systems that can integrate deeply, scale dynamically, and operate within tight legal boundaries.

Opportunities & Restraints

Opportunities

• 5G Rollout and IoT Interception Needs As countries accelerate 5G deployments, lawful interception systems need to adapt to low-latency, high-volume, and device-dense environments—unlocking new business for OEMs and software vendors.

• AI-Driven Real-Time Surveillance There's growing demand for machine learning-enhanced interception that not only collects but also contextualizes voice, message, and metadata in real time, especially for counterterrorism and cybersecurity.

• Emerging Markets Modernizing Surveillance Laws Nations across Africa, Southeast Asia, and Latin America are drafting or updating surveillance regulations, opening new markets for LI platform providers with low-cost, scalable solutions.

 

Restraints

• Regulatory Ambiguity and Public Backlash In many democracies, lawful interception initiatives face privacy challenges and legal hurdles , especially when legislation is vague or public trust is low.

• High Capital Investment for Full-Scale Deployment Setting up a compliant, secure, and multi-network interception system requires significant upfront investment , often limiting adoption in mid-size telecoms or developing regions.

With strong tailwinds from national security budgets, the market is poised to grow rapidly—but only those vendors who balance innovation with regulatory and ethical compliance will gain long-term traction.
