Smarter Voice Networks Made Easy with SBC API Integration
ProSBC is a high-performance, carrier-grade Session Border Controller (SBC) trusted by service providers worldwide. Its strength lies in a powerful scripting engine at the core of every ProSBC Application Programming Interface (API). This engine leverages over 100 call parameters to create intelligent, highly customizable call flows. When these scripts interact with external services—such as fraud detection platforms, routing engines, or analytics tools—they become dynamic API integrations that enhance real-time decision-making.
Whether you’re building custom routing logic, enabling fraud detection, or implementing compliance tools like STIR/SHAKEN, ProSBC APIs give you the flexibility to connect your Session Border Controller to the rest of your telecom stack.

REST API Integration
Enables external systems to interact with ProSBC using HTTP methods (GET, POST, PUT, DELETE) for call decisions, provisioning, and monitoring.
ProSBC supports REST API integration during SIP call processing, enabling interaction with external systems in real time. This functionality is driven by ProSBC’s scripting engine, which allows for precise control over when and how API calls are executed using more than 100 available call parameters, such as caller ID, dialed number, or SIP headers.
This approach allows service providers to implement use cases like fraud prevention, branded calling, call reputation analysis, SBC provisioning, and data-driven call routing. Because the API logic is handled within the script, integration is highly flexible and can be tailored to meet specific operational or business requirements.
API calls are made during the signaling phase of the call, ensuring that decisions are made quickly and do not affect media quality. The result is a scalable, reliable way to enhance call handling with external data and services.

Use Cases:Fraud Prevention, Branded Calling, Call Reputation, SBC Provisioning
ProSBC integrates with STIR/SHAKEN authentication services using REST or SIP Identity headers. It signs and verifies calls to prevent spoofing and comply with regulations. Prebuilt scripts simplify deployment with common platforms. Use Cases:STIR/SHAKEN Compliance, Branded Calling More details: STIR/SHAKEN Integration
Routing Script Engine
ProSBC’s routing script engine uses the Ruby programming language to create flexible, browser-based call routing logic without compilation. It supports built-in scripts for use cases like least-cost routing, round-robin, SIP trunking, and over-subscription, and allows providers to modify routing behavior easily through the web interface. Use Cases: Advanced Routing, Service Chaining More details:Routing Scripts
CNAM, LNP, and Toll-Free Lookup
ProSBC integrates with services like TransNexus ClearIP to perform CNAM, LNP, and toll-free number lookups via REST API during call setup. The SBC sends call data to ClearIP, which returns caller name, porting status, and robocall analytics that ProSBC can use to adjust routing or caller display. This enhances call accuracy, fraud prevention, and caller trust in real time. Use Cases: LNP Routing, CNAM Delivery, Toll-Free Call Handling More details:CNAM and Robocall Analytics with ClearIP
Real-Time Billing and CDR Integration
ProSBC generates customizable Call Detail Records (CDRs) and supports external charging triggers. These can be exported or sent via API for billing and reconciliation. Use Cases: Billing More details:CDR Configuration
Ready to Get Started With SBC API Integration?
Whether you’re integrating a fraud detection engine, enabling branded calling, or adding advanced routing logic, ProSBC APIs give you the control and flexibility to build the voice services your business needs.
Session Border Controller API integration empowers service providers to make smarter, real-time decisions by connecting their Session Border Controller to external systems like fraud detection platforms, routing engines, and analytics tools. With ProSBC’s scripting engine leveraging over 100 call parameters, APIs enable dynamic call flows for various use cases, for example, branded calling, STIR/SHAKEN compliance, least-cost routing, and real-time billing. Because decisions are executed during call signaling, providers gain flexibility without sacrificing performance, improving security, compliance, efficiency, and customer trust.
How does REST API integration improve call handling with ProSBC?
REST API integration improves call handling with ProSBC by enabling real-time interaction with external systems during SIP call processing. Using over 100 available call parameters, such as caller ID, dialed number, or SIP headers, ProSBC can trigger API calls to fraud detection platforms, routing engines, or analytics tools before the call is connected. This ensures smarter, data-driven call decisions without affecting media quality, helping service providers enhance security, optimize routing, and deliver a more reliable calling experience.
How does API integration impact call quality and performance?
API decisions happen during the call signaling phase, so routing, fraud checks, and compliance measures are completed before the call is connected. This ensures security and efficiency without affecting audio quality.
