Spoofing Protection

Ensure integrity and customer trust by detecting and preventing Caller ID (CLI) spoofing.

Secure your voice traffic

Implement a Caller ID spoofing protection system based on our proven carrier-grade technologies to eliminate voice fraud. Our Spoofing Protection solution enforces your anti-spoofing policies on every incoming call, validating the calling number against DNO and allow/block lists, interconnect prefix rules, number portability data and its actual status in the network, so only legitimate calls reach your customers.

Inbound protection

Seamlessly apply verification policies to inbound interconnect calls with configurable actions like Block, Redirect and Pass.

Inter-operator trust

Verify calling numbers directly with peer operators over a bidirectional REST and gRPC API and answer their queries about your own subscribers.

Modular by design

Easily expand features with modular architecture, tailor the platform to your verification flows and integrate it with your core network.

Policy control

Manage allow and blocklists at scale with versioning, rollback and four-eyes approval on every change as well as an emergency bypass that opens traffic instantly when you need it.

Configurable verification flow

Build your own decision logic: choose which checks to run, in what order and how much each signal weighs, with separate rules per trunk, peer and number range. Validate any change against live traffic in monitoring mode before it starts blocking calls.

Core network interrogation

Query the HLR/HSS to establish where the calling number actually is and whether it’s already engaged in a call, with per-source caching and passive event analysis reused to cut interrogation volume and speed up verification.

Monitoring and analytics

Keep track of real-time performance metrics, including live traffic overview, verdict distribution, spoofing trends, top blocked callers/ranges and platform health on one dashboard, with every figure traceable to the calls behind it.

Alerting

Detect spoofing campaigns as they start, with configurable alert rules per peer, trunk and number range, and reconstruct the exact policy in force when an incident occurred.

Overload protection

Protect your system against incoming traffic overflow with in-built rate limiter, per-peer throttling and configurable error treatment.

Audit logs

Store every verdict together with the signals that produced it in a correlated log, so any decision can be reconstructed months later and tampering is evident.

Deployment models tailored to your business

A customized approach to clients, fast response times and adaptability ensure seamless implementation, regardless of location, in-house infrastructure and company culture.

Cloud-based

Voice Anti-Spoofing is built to run anywhere: in a containerized or virtualized environment, on your own infrastructure or on major public clouds. Launch the solution in weeks instead of months, with no hardware lead time and reduced CAPEX – and keep the signaling components close to your core network in a hybrid configuration where latency or data residency requires it.

On-premises

Designed as products from day one, Amplitiv solutions are flexible enough to be able to satisfy the needs of most operators “off the shelf”, without any customizations. Our highly specialized deployment teams, capable of swiftly launching our services, have a proven track record of successfully deploying our systems in production environments within three months of a purchase order.

Turn-key customizations

Our development team is ready to adjust our solutions to fit the needs of individual operators with a specific vision of the system. We customize and fine-tune our components to clients’ needs, as well as develop custom applications and integrations that extend baseline products.
