Hybrid Asterisk PBX Setup

I’m rolling out a new Asterisk-based PBX that spans both an on-prem rack server and a small cloud instance. I need a specialist who can take the project from a clean slate to a fully functional, production-ready system.

Here’s what I’m expecting:
• Complete installation of the latest stable Asterisk on each node (one local, one cloud) with SIP trunks registered and ready.
• Seamless call routing between sites, extension dialing, voicemail, IVR, and basic queue logic operating flawlessly across the hybrid topology.
• Secure configuration—TLS/SRTP, strong authentication, sensible firewall rules, fail-over settings between the two servers.
• Real-time monitoring and alerting set up (Nagios, Zabbix, Grafana, or a tool you’re comfortable with) so I can track call quality, trunk status, disk/CPU, and receive instant notifications on issues.
• Clear, concise hand-over documentation and a quick walkthrough so I can maintain day-to-day tasks internally.

Acceptance criteria:
• Both servers pass test calls (internal, external, fail-over) without packet loss or noticeable latency.
• All configured services appear clean—no critical alerts—on the monitoring dashboard for 48 consecutive hours.
• Documentation is delivered in an editable format and accurately reflects the live environment.

If you’ve built hybrid Asterisk systems before and can move fast while keeping things tidy, let’s get started.
