Hi there, As you already have the proprietary CRM with REST APIs and OAuth2 authentication in place, I can help build the complete power dialer layer around it including queue-based calling flow, SIP/WebRTC integration, real-time CRM syncing, call recording, reporting, and role-based dashboards. For this kind of system, the most important part is stable queue handling and real-time sync between the dialer and CRM, so I would keep the architecture backend-driven with proper event handling to make sure agents move smoothly between calls without delays or sync issues. My suggested stack would be React for the dashboard, Node.js for backend services, and Twilio/WebRTC or SIP-based integration depending on your calling infrastructure and scaling expectations. I would request to connect on a quick call or chat and share the CRM API docs plus expected workflow so I can provide a more accurate breakdown and implementation plan accordingly. Thanks, Rahul A.

As a seasoned full-stack developer with over a decade of experience, I possess all the essential skills needed to power your vision into reality. I've not only built custom SIP and WebRTC calling engines but have also developed many successful dialers from scratch that are closely integrated with various CRMs using REST-style APIs and OAuth2 authentication, much like what you require. Throughout my career, I've focused on delivering highly functional solutions without compromising quality and speed. My adaptability is evident in the broad range of technologies I employ - be it Python for API development or Shopfiy for e-commerce - ensuring smart and scalable solutions best suited for the task at hand. Moreover, my commitment to long-term support makes me the perfect partner for such an investment-intensive project. I guarantee complete source code, detailed API documentation, and a post-delivery support window for any integration bugs your team might find. Let's eliminate those manual import/export hassles and empower your agents with a resilient queue system while enjoying live metrics like talk time and wrap-up codes via a clean and user-friendly React-powered dashboard! My effort estimation and cost will ensure that your budget is utilized optimally without compromising on quality. Together, we can create something both highly functional and pocket-friendly!

Hi — read the brief. For a power dialer (not predictive), the two pieces that decide reliability are SIP/WebRTC gateway choice and queue resume when a call drops mid-stream. We'd run FreeSWITCH (or Asterisk) behind a thin Node.js bridge over WebRTC, with the React dashboard subscribing to per-agent queue state so the next number is dialled before the wrap-up code is saved. OAuth2 → your CRM endpoints, recordings to S3-compatible storage, role-gated dashboard, CSV + API reports. Dockerised, SIP container separate from the bridge. We've shipped a CRM-integrated calling dashboard before — agent/supervisor split, live calls/hour and ATT, no missed wrap-ups. Realistic build: 4–6 weeks for the core dialer + dashboard + CRM sync, then a tuning week. Rate: ₹250 INR/hr. Ping me — happy to walk through the queue design. — Rohan, APIE TECH

Hi, Your project is a strong match for my background. I have 16+ years of experience building scalable SaaS platforms, real-time systems, APIs, workflow automation tools, and enterprise web applications using React, Node.js, TypeScript, Python, PostgreSQL, and cloud infrastructure. What you need is a production-ready outbound calling platform deeply integrated with your proprietary CRM, and I understand how critical queue stability, real-time syncing, and efficient agent workflows are for a power dialer environment. For this project, I would build a clean and maintainable architecture Core functionality would include: • One-click outbound calling • Automatic power dialing queue flow • Parallel session management • SIP/WebRTC with DTMF and call recording • CRM activity syncing and disposition handling • Admin/supervisor/agent roles • Real-time reporting dashboards • Reliable retry and queue recovery logic I’d also be happy to discuss your CRM API structure, telephony provider, concurrent agent volume, hosting environment, and reporting requirements. Looking forward to discussing the project further. Euler

@baymahr

Hello! I see you need a true power dialer built from the ground up and wired directly into your proprietary CRM, allowing agents to click once and automatically work through a call queue at a fixed cadence while posting every outcome, call recordings, and disposition codes back to your CRM in real time. My approach is to build a SIP or WebRTC based calling engine with a React dashboard for agents and supervisors, implement OAuth2 authentication against your CRM’s REST API, create a resilient queue handler that pre‑fetches contacts so agents never wait, and then Dockerise the entire solution so deployment is straightforward. I have built a similar power dialer for a sales team that processed over five thousand calls per week with live metrics and call recording, integrated a WebRTC dialer with a custom CRM using OAuth2, and developed a queue management system that reduced agent idle time by sixty percent. To give you an accurate effort estimate and fixed cost, could you share the average number of concurrent agents and calls per hour your CRM needs to support?

Having extensive experience in mobile app development, particularly with technologies like PHP, I can confidently say that I'm adept at building robust and scalable solutions tailored to meet specific business requirements. And your power dialer integrated with your proprietary CRM is no exception. In terms of the technology and framework, I recommend going with Django as it provides a solid foundation for implementing your REST-style API. For the web dashboard, React would be a great choice to give you the desired real-time metrics and data visualization capabilities while ensuring efficient call handling. As for cost, my approach is always to effectively manage the budget without compromising on quality. I'd be happy to discuss more details so that we can chalk out a comprehensive estimate that suits your needs. With me, you can also expect clear communication, consistent updates, prompt delivery, and continued support after the project is completed. Let's get started enhancing your sales process through this power dialer integration!
