Hi A common challenge in hosted PBX reseller platforms is keeping multi-tenant isolation, real-time billing, and client self-service perfectly synchronized at scale. I have hands-on experience building FreeSWITCH and FusionPBX multi-tenant environments with strict domain isolation, role-based access, and enterprise call-center features. I would integrate CGRateS for true real-time charging, balance enforcement, and fraud protection while keeping billing logic modular and auditable. On the portal side, I build clean React dashboards backed by Python APIs to expose CDRs, balances, SIP credentials, and service controls securely. WebRTC calling, call recording, and reporting are implemented with hardened security layers including SSL, Fail2Ban, and firewall rules. Payment integrations are handled via webhook-driven top-ups so balances update instantly without manual intervention. The result is a production-ready UCaaS platform that is scalable, reseller-friendly, and fully owned by you. Thanks, Hercules
