The problems iStar
solves
This product was built to solve the recurring operational and development challenges found in real environments like the ones below.
A fan-artist video call platform where fans wait their turn in a queue and artists pick fans from a dashboard to run 1:1 video calls. It provides Agora RTC-based real-time calls and a WebSocket waiting room. Existing solutions were either not operator-friendly or built in a way that piled up maintenance costs. UNISYS redesigned this into a product that's owned all the way through operations.
Key Features
The core features iStar provides. Every feature is delivered in an operable form.
Real-time waiting room
Fans join a virtual queue over WebSocket to see live waiting counts and their turn, automatically receiving an Agora channel and token when it's their turn.
Artist dashboard
Artists see the waiting list in real time and pick the next fan to start and end calls. An artist-driven flow runs one call at a time.
1:1 video calls
Real-time video calls powered by the Agora RTC SDK, with channel tokens issued securely on the server.

Create and manage events (fan meetings); fans enter via participation-code verification.
Separate auth model
Separate JWT authentication for fans (participation code) and artists (username/password) controls access.
