ViciDial Install & Firewall Setup

I already have a Contabo server standing by and simply need a clean, production-ready ViciDial stack on it. The job covers:

• Installing the latest stable ViciDial (with Asterisk and its dependencies) from scratch.
• Optimising the underlying Linux distro you feel is most reliable for call-centre workloads.
• Hardening the box with a well-tested firewall configuration—CSF, UFW, iptables, or a similar solution is fine—as long as only the ports Vicidial, SSH and web administration actually require remain open.
• Verifying that the web interface, database, and telephony services all start automatically after a reboot and that calls can be placed through a demo campaign.
• Supplying a concise hand-off sheet: all commands run, credentials created, and the port map.

The server will be handed over with root SSH access. I will test by loading a small lead list, logging an agent in, and confirming audio both ways. Deliverables are complete once that succeeds without errors and the firewall passes an nmap scan with only the expected ports visible.
