Hi, I can develop your Android VoIP calling app along with a secure web-based admin portal for user and call management. The system will support user login, direct VoIP calling to phone/mobile numbers, assigned/verified custom caller IDs, and detailed call logging (number, time, duration, IP where available). The admin panel will allow only authorized admins to create/manage users, assign caller IDs, and review call history through a clean dashboard. The Android app will include login, dialer, calling via SIP/WebRTC integration, and optional personal call history. The backend will provide secure APIs and database storage for users, caller ID mapping, and logs. Custom caller ID will be implemented only through compliant VoIP providers (e.g., Twilio/Plivo/SIP trunk) to ensure legitimacy and reliability. The stack can be Android (Kotlin), backend (Node.js/Django), and responsive web admin (React or lightweight UI). I will deliver full source code for app, backend, and admin portal with setup documentation and deployment guidance so the system is production-ready and extensible.

Hello, You’re looking for a structured VoIP solution — not just an app, but a controlled system with admin authority, caller ID management, and proper call tracking. I can build this with: • Android App (Kotlin or Flutter) • SIP/WebRTC-based VoIP integration • Secure backend (Node.js or Python) • Web-based Admin Portal (React + REST APIs) • MySQL/PostgreSQL for structured logging Admin Portal will include: - Controlled user creation & management - Custom Caller ID assignment - Editable user details (secure password handling) - Detailed call logs (IP, number, duration, timestamp) Android App will support: - Secure login - Direct VoIP calling with assigned Caller ID - Call history (scalable for advanced version) Architecture will be designed for stability, low-latency calling, and clean separation between calling engine and management layer. Proper authentication and logging structure will be implemented from day one. Before development, we should clarify SIP provider / VoIP gateway preferences to ensure caller ID compliance. Once scope is fully aligned, we can comfortably finalize timeline and budget — my priority is delivering a stable, production-ready system rather than rushing execution. Looking forward to discussing your requirements in detail.
