Public Video Call Phone System
Budget: $1,500 – $3,000 USD
I need a complete solution that lets people walk up to a public device, place a video or voice call, and pay for the time they use—much like a payphone, but for modern smartphones.
Here’s the workflow I have in mind: a caller at the public phone initiates a video or voice call, the recipient answers on an app installed on their own phone, and the call time is deducted from the caller’s prepaid balance. To make this work, I require three tightly-integrated components.
• Dual-platform calling apps
– One app pre-installed on the public phones for callers
– A companion app for recipients on both iOS and Android
– Core features: high-quality video and voice calling, automatic time/balance tracking, and clear prompts when credit runs low
• Credit reload & balance app
– Users must be able to top up and monitor their remaining minutes directly inside the app; no web portal or physical kiosk is planned at this stage
• Central management system
– Allows me to register, configure, and remotely monitor each public phone
– Real-time call logs, credit usage reports, tariff editing, and over-the-air updates are essential
Everything should share a single backend so balances stay synchronized. Reliability on spotty public connections is important, so please factor in call quality management and offline balance caching. An admin dashboard, API documentation, and clear build instructions will form part of the final hand-over.
