#!/usr/bin/env bash
#
# CSVox PBX one-liner installer.
#
# Usage:
#   bash <(curl -fsSL csvox.sh)
#
# What this does:
#   1. Detects the distro codename (trixie, noble) — fails on anything else.
#   2. Adds packages.sury.org/php (Sury) — provides PHP 8.4.
#   3. Adds repo.csvox.com — provides csvox-freeswitch + csvox-pbx.
#   4. apt-get install csvox-pbx (which pulls csvox-freeswitch as a dep).
#   5. Prints next-steps with the URL to open the in-app /setup wizard.
#
# Requirements:
#   - Debian 13 (trixie) or Ubuntu 24.04 (noble), amd64.
#   - root or sudo.
#   - Outbound HTTPS to packages.sury.org and repo.csvox.com.
#
# Idempotent: re-running won't error if the apt sources are already in place.
# Re-running WILL upgrade csvox-pbx if a newer version is published.
