Reference architecture

A modular flow from UI → API → Messaging Core → GSM Modems. Queue workers pull jobs, apply templates, send via AT commands, and push delivery receipts back to API consumers.

  • UI: Dashboard + Campaign Manager
  • API Layer: REST + Webhooks + Auth
  • Messaging Core: Queue, Router, Templates
  • Device I/O: AT control, Health checks, SIM rotation

Deploy on‑prem, Docker, or edge box; export metrics via Prometheus.
