Complete IPRN VoIP Switch Development

@ozbas

With over a decade of experience under my belt, I am confident in my ability to develop the complete IPRN/VoIP switch you're seeking. My skills go beyond just development, but extend to API Development and Database Design as well, ensuring a comprehensive understanding of the project. Not only have I used similar carrier-grade platforms like FreeSWITCH in the past, but I've actually built and deployed an operational IPRN system. My prior projects have always emphasized stability and feature-completeness over speed, which aligns perfectly with your requirements. Proving the quality of my work is no problem- you'll find an extensive portfolio at your disposal showcasing my ability to deliver functional SIP trunks, efficient routing/LCR logic, precise billing modules, and more. For me, successful completion isn't just delivering on time or ticking off requirements - it's about creating something that not only meets your needs but exceeds your expectations-margin. I look forward to discussing your project in further detail and offering you a tailored solution that make deftly handles all the elements of this task effectively. Let's create a powerful product that goes above and beyond everything you could hope for!

Hi there, I understand you need a complete, carrier-grade IPRN switch. Operationally, this involves accepting traffic from various SIP trunks, using a dynamic LCR engine to route calls based on prefix and cost, and performing real-time rating and billing for each session. The system must generate accurate CDRs while providing segregated web panels for admins (to manage carriers/rates), resellers (to manage their clients), and end-clients (to view usage). Technical approach: We will use FreeSWITCH as the core media server for SIP handling and call control. A robust backend (e.g., Spring Boot) will manage the business logic, REST APIs, and the multi-level web panels built in React. PostgreSQL is ideal for storing rate tables, user data, and CDRs. The backend will interface with FreeSWITCH via the Event Socket Library (ESL) for real-time control. Core modules: Carrier SIP Trunk Manager, LCR & Dynamic Routing Engine, Real-time Billing & CDR Processor, Multi-Tenant Portals (Admin, Reseller, Client) with role-based access, and SMS Interconnect Gateway. Relevant systems: We have delivered a custom call management system that integrated an Android dialer with a FreeSWITCH call server for call control, recording, and logging. This project provided us with direct, hands-on experience deploying and integrating FreeSWITCH for a live business application. Implementation strategy: We'll begin by setting up the core FreeSWITCH routing and CDR generation. Next, we will build the billing engine and the admin panel, followed by the reseller and client portals. This iterative approach ensures the core telephony functions are stable before adding management layers. Regards, Rohit

Hey, I will deliver your IPRN switch on FreeSWITCH with carrier SIP interconnections, dynamic LCR routing with rate tables, real-time CDR and billing, and the full admin/reseller/client panel stack with role-based access enforced at the API level. On a similar carrier-grade build, I implemented multi-tenant data isolation across reseller and client tiers so billing and CDR records stay accurate even under high concurrent call volume. I will apply that same architecture here. Questions: 1) How many carrier SIP trunks do you need connected at launch, and do you have existing interconnect agreements ready? 2) For the SMS interconnect, are you routing through SMPP or an HTTP-based provider? I am happy to share relevant proof of past work in our chat. Looking forward to talking through the details. Kamran

I understand you require a complete IPRN/VoIP switch development, including Carrier SIP interconnections, dynamic LCR routing, real-time billing and CDR, multi-level admin/reseller/client panels, and SMS/voice interconnects. I have successfully built and deployed similar carrier-grade VoIP switching solutions in live environments, including one for a major international carrier that handled millions of minutes daily. My proposed solution will leverage FreeSWITCH as the core platform, configured for high availability and performance. I will develop custom modules for dynamic LCR routing based on cost and availability, implement a robust real-time billing engine integrated with a PostgreSQL database for CDR storage, and build intuitive web interfaces for admin, reseller, and client management using React and Node.js. SMS and voice interconnects will be handled via standard SIP and SMPP protocols. Regarding the multi-level panels, what specific reporting granularity is expected for the reseller and client tiers beyond basic call summaries and balance information? Ready to start as soon as you confirm scope.

@techsty2014

Hello there, We will deploy a FreeSWITCH-based IPRN switch with carrier SIP interconnections, dynamic LCR routing, real-time billing with CDR export, and multi-level panels (admin, reseller, client). For routing, we will build rate tables that update per-prefix LCR in real time. Each call hits the lowest cost route first, fails over automatically, and logs a CDR with margin calculated at call end. Role-based panels will let resellers manage their own clients and rates independently. We are happy to share relevant examples in our chat. A couple of quick things to confirm: 1) How many carrier SIP trunks do we need to support at launch? 2) Should billing settle in a single currency, or do you need multi-currency support across reseller accounts? The number quoted here is a starting estimate. Looking forward to talking through the details. Faizan

@cuyodigital

Hello, I’ve reviewed your requirements and I can help you build and integrate this system cleanly and efficiently into your existing setup. I have solid experience in full-stack development (React, Vue, Laravel, Node.js) and working with existing codebases, APIs, and deployments. I focus on clean architecture, reusable components, and stable production-ready builds. One performance improvement I often implement is reducing frontend load time by optimizing bundle size (code-splitting + lazy loading) and caching API responses, which significantly improves Lighthouse scores and user experience. I can start immediately and work step-by-step with your milestones or staged delivery process. Let me know if you’d like me to begin with an initial setup or code review. Thanks

@hassanmustafa01

Hello, I understand your need for a robust, carrier-grade IPRN/VoIP switch that delivers operational stability and comprehensive features tailored for multi-tier management and real-time billing. Given the critical nature of telecom infrastructure, my approach prioritizes business continuity and scalability over rapid delivery. Key approach: - Backend: Build on FreeSWITCH or a proven platform, ensuring secure SIP interconnections, dynamic LCR routing, and precise CDR generation with export capabilities. - Frontend: Develop intuitive, role-based web panels for admin, reseller, and client management, focusing on usability and access control. - Real-time: Implement reliable billing and SMS/voice interconnect tested on live SIP trunks with end-to-end verification. I have successfully delivered similar turnkey IPRN switches in live environments, including documented deployments and client training. I can share detailed case studies and demo access upon request. Could you clarify your preferred hosting environment and any specific compliance or security standards to observe? Also, do you have existing SIP providers or expect assistance in carrier onboarding? Looking forward to aligning on your business goals and delivering a stable, scalable solution. Best regards.
