Hi there, I have read your project requirement. You need a complete SIM-based business calling CRM system with Android app, admin panel, website, backend APIs, and auto dialer functionality similar in workflow to Superfone but fully custom-built. We will build the Android app in Flutter (with native Android modules for SIM calling), backend using Node.js + Firebase (or scalable VPS-based APIs), and a React-based admin panel + website. SIM-based calling will be handled via Android Telecom APIs (ACTION_CALL) with call logs captured locally and synced to the backend. Auto dialer will be implemented with controlled foreground services due to Android background restrictions. The system will include CRM, lead distribution, campaign dialling, and real-time reporting with role-based access. Questions: ========== Do you need call recording functionality (note: device/legal limitations apply)? Will agents use company-provided devices or their own phones? Do you need WhatsApp/SMS integration inside CRM? Expected scale (number of agents & daily calls)? Best Regards, Srashtasoft Team

Interesting project, I will build your SIM-based business calling CRM — the Android app with auto dialer and click-to-call for agents, a CRM backend with lead management, call logging, follow-up tracking, and campaign-based calling, an admin panel with reports and role-based access, and a marketing website with pricing and lead capture. For the SIM-based calling, I will use Android's TelecomManager API to initiate and track calls through the device SIM directly. The key challenge is background calling restrictions on Android 10+ — I will handle this with a foreground service and proper notification so the auto dialer keeps running reliably during campaigns without getting killed by the OS. Questions: 1) How many agents will use the system at the same time — this affects how the lead distribution and call queue should be designed? 2) Do you need call recording as part of the call logging, or just metadata like duration and status? 3) For the auto dialer, should it wait for agent availability between calls or dial continuously with a set delay? Ready to start whenever you are. Kamran

@RajAbhisek

Hi, I am a full-stack and Android developer from India with 6+ years of experience building CRM platforms, calling systems, and business communication tools. I have worked on dialer-based applications, lead management systems, and role-based admin panels. Let me address the SIM-based calling question directly. On Android, SIM-based calling uses the native telephony manager and call log APIs. The app can initiate calls through the real SIM, log call details, track duration, and sync data to the backend automatically. The main limitation compared to virtual numbers is that background auto-dialing has Android restrictions after version 10, but this can be handled with foreground service implementation and proper permissions to keep the dialer running reliably. For the auto dialer I would build a campaign-based system with agent-wise lead distribution, retry logic, and call status updates synced in real time to the CRM. My stack for this project would be Flutter for the Android app, Node.js with Express for the backend APIs, PostgreSQL for the database, and React for the admin panel and website. The CRM would include lead management, notes, follow-up reminders, call history, and role-based access for agents and admins. Deliverables would include the Android APK with source code, admin panel, website, backend APIs, deployment support, and post-launch assistance. Timeline and budget available after a short discussion on final feature scope. Happy to start soon. Thanks, Raj

Hi there, Strong alignment with this project comes from building CRM, dialer systems, and mobile-first platforms with real-time communication workflows and scalable backend architecture. Clear understanding of developing a SIM-based calling CRM with Android app, auto dialer, lead management, admin panel, and full backend APIs. Hands-on expertise with React/Node, Android (native/React Native), and telecom integrations ensures efficient call logging, campaign dialing logic, and role-based systems. Risk is minimized through clear handling of Android SIM limitations (call intents, background restrictions), structured dialing queues, and scalable backend design. Available to start immediately happy to share architecture, feasibility, timeline (6–8 weeks MVP), and cost breakdown. Recent work: https://www.freelancer.com/u/chiragardeshna Regards Chirag

@KarthikTechCon

Hi, I’m Karthik with 15+ years of experience building scalable CRM, telephony, and mobile-first platforms. Your requirement for a SIM-based business calling CRM (similar workflow to Superfone but independently built) is clear and aligns well with my expertise. How I’ll approach this: • Android App (Kotlin): Native SIM-based calling using Telecom APIs, call logs, click-to-call, agent dashboard • Auto Dialer: Campaign-based dialing, queue management, retry logic (handled with foreground services due to Android background restrictions) • CRM System: Lead lifecycle, notes, tags, reminders, call tracking, role-based access • Backend: Scalable microservices (Node.js / .NET Core), REST APIs, PostgreSQL, Redis for queues • Admin Panel + Website: React-based UI with analytics, reports, and lead capture SIM-Based Clarification: • Uses device SIM via Android TelecomManager • No true background auto-calling (OS restriction) → handled via controlled foreground dialer • Call tracking via call logs + app sync • Better cost control vs virtual numbers, but limited central control compared to VoIP Experience: Built CRM + dialer systems, lead automation platforms, and telecom-integrated apps for sales teams. Timeline: 6–10 weeks (phased delivery) Support: Deployment + post-launch maintenance included Happy to discuss architecture and provide a demo approach. Warm Regards, Karthik B Resonite Technologies
