Public Video Call Phone System

@infowider11

Hi, I can build a complete pay-per-minute voice/video calling platform with public-phone and recipient mobile apps, a shared wallet system, secure balance management, and a centralized admin dashboard. The solution will include real-time call tracking, automatic credit deduction, remote device management, OTA updates, reporting, and a scalable backend optimized for reliable performance even on unstable networks. A couple of quick questions: * Do you have a preferred calling technology such as WebRTC, Agora, or Twilio, or would you like me to recommend the best option? * Will users purchase credits through in-app payments, or do you plan to integrate external payment gateways as well? I have experience developing real-time communication platforms, Flutter/React Native mobile apps, secure backend systems, payment integrations, and enterprise dashboards with scalable architecture and production-ready deployments. Let’s chat.. Thanks,

Hi, This is a real-time billing and call-control project, not just a calling app. The main challenge is keeping balances synced across the public device, recipient app, and admin system while handling weak connections without double-charging or losing call time. I’d also focus on the low-credit and call-end flow, since that affects user trust. My first priority would be the core architecture: public caller app, recipient iOS/Android app, and a backend for authentication, balances, tariffs, call logs, and device state. Then I’d build the prepaid wallet flow, live usage tracking, and remote device monitoring to ensure stability before adding extra features. I’d also provide clean API documentation and build steps for each app. Key work areas: Public caller flow Recipient calling flow Top-up and balance tracking Admin dashboard and device control Call logs, tariffs, and sync logic Timeline-wise, I’d start with architecture and core billing logic first, then move into app flows, admin tools, and testing for sync and edge cases. One question: should charging stop strictly by connected call time, or should there be a setup/connection fee before the call begins?

Hi — Elias here from Miami. This is really a prepaid communication platform, not just a calling app. The key challenge is keeping calls, balances, tariffs, and device status synchronized across public phones, recipient apps, and the admin system without allowing duplicate charges or balance errors during poor connectivity. I’d structure it around one secure backend with WebRTC-based voice/video calling, real-time session metering, prepaid wallet ledgers, push notifications, and centralized device management. The public-phone app would use a locked-down kiosk mode, while recipients would use a simpler iOS/Android companion app. For unreliable connections, I’d use adaptive call quality, reconnection handling, and limited offline balance caching with server-side reconciliation. Every charge would be tied to a unique call session so retries cannot deduct credit twice. I’ve worked on real-time platforms involving calling, payments, device control, usage tracking, and admin reporting where reliability and auditability were essential. A few questions to better understand the scope: Q1 – What hardware and operating system will the public phones use? Q2 – Should recipients be able to call public devices back, or only receive calls? Q3 – Which countries, currencies, and payment methods must top-ups support initially? Looking forward to hearing from you.

Hi there, I understand the system: a user at a public terminal initiates a call, your backend verifies their balance and connects them to a recipient's app via WebRTC. Credit is deducted in real-time, with low-balance alerts and automatic call termination. A central dashboard will provide full control over the device fleet, tariffs, and reporting. Technical approach: A unified backend (Node.js or Spring Boot) with PostgreSQL. Flutter for both the public kiosk and recipient iOS/Android apps. WebRTC for calls, using a media server or a service like Twilio. Admin panel in React.js. Core modules: - Public Kiosk & Recipient Calling Apps - Integrated Wallet & Payment System - Real-time Billing & Session Control Engine - Remote Device, Tariff & Reporting Dashboard Relevant systems: We've built an Android call management solution with FreeSWITCH server integration. We also developed SecureCom, a cross-platform encrypted calling and messaging application. Implementation strategy: Start with an MVP: core backend, wallet, and a functional P2P call. Then layer on the real-time billing and the admin dashboard, followed by robust testing for network instability before handover. Regards, Rohit

This looks like a great fit, Hi, I will deliver your public video call phone system as three integrated apps sharing one backend: the caller kiosk app, the iOS/Android recipient app, and the admin dashboard with real-time call logs, tariff editing, and remote device management. For a similar prepaid calling platform, I built offline balance caching that kept call sessions accurate even when connectivity dropped mid-call, preventing disputed charges entirely. Questions: 1) For the caller kiosk app, are the public devices running Android, or a locked-down custom OS? 2) Will tariffs be flat per minute, or do you need tiered pricing (e.g., video calls costing more than voice)? Share your preferred tech stack or any existing backend work and I will map out the architecture this week. Looking forward to discussing further. Best regards, Kamran

@DrSyafiq

You're building Public Video Call Phone System, where the real delivery risk is usually in the workflow details, not just the feature list. I have handled similar systems where the important part was turning a broad brief into a reliable working version. My approach would be to first isolate the highest-risk workflow in the brief, then deliver a small working milestone that proves the architecture before expanding the rest. For this project, I would focus especially on: - core workflow risks and acceptance criteria - integration points and edge cases - milestone planning and handover clarity If helpful, I can outline the first milestone around the riskiest part of the build before we start. Best, Dr. Syafiq

@Aaleen110

I understand you need a public video call phone system integrating a pre-installed caller app on a public device with a companion app on the recipient's smartphone, all managing prepaid call balances. I recently developed a similar system for a retail kiosk, enabling secure transactions and real-time user account management. My solution will involve building the caller app using native Android (Kotlin) for the public device and the recipient app using React Native for cross-platform compatibility. The backend, handling payment processing and call session management, will be built with Node.js and PostgreSQL, integrating with a WebRTC service for real-time audio/video streaming. Users will see a clear interface for initiating calls, viewing their balance, and managing their account within the recipient app. How will the public devices handle the initial payment or balance top-up for a caller before a call is initiated? Ready to start as soon as you confirm scope.

@techsty2014

Hello, We will build your public video call phone system: caller app, recipient app (iOS and Android), credit reload module, and a central admin dashboard, all sharing one synchronized backend. For call reliability on spotty connections, we will implement adaptive bitrate switching with a fallback to voice-only mode. Offline balance caching will use local storage that syncs once connectivity returns. This prevents dropped sessions and keeps credit records accurate. A couple of quick things to confirm: 1) Which payment method should the credit top-up support (Stripe, local mobile money, or another gateway)? 2) Will the public phone devices run Android, or is a different OS planned? The number quoted here is a starting estimate. The exact cost and timeline will be confirmed after we go through the full scope together. Looking forward to potentially working together. Thanks, Faizan
