The previous fix used the {host} Caddy placeholder for X-Forwarded-Host,
but confirmed live it still evaluated to the upstream Authelia's own
hostname rather than the original site's — Caddy appears to rewrite the
outgoing request's Host to the upstream target before header_up
placeholders resolve for a scheme-qualified remote upstream, so {host}
echoed back the already-rewritten value. Since this site block only ever
serves one domain, hardcode it instead of depending on placeholder timing.

# Easy Asterisk PBX + coturn — DigitalOcean droplet edition
|
||
|
||
Self-hosted SIP PBX using Easy Asterisk with a coturn TURN/STUN server for
|
||
NAT traversal, sized and secured for a public DigitalOcean droplet. For a
|
||
home/LAN box with VLAN support, use \`~/docker/asterisk\` (services/asterisk.sh)
|
||
instead.
|
||
|
||
## Droplet sizing
|
||
|
||
Asterisk + coturn is light for a handful of SIP extensions and personal use.
|
||
|
||
| Plan | vCPU | RAM | Good for |
|
||
|--------------------------------|------|-------|----------------------------------------|
|
||
| Basic (regular), \$4/mo | 1 | 512 MB | Works — this installer adds a 2GB swapfile automatically to cover it. Fine for a couple of extensions and light personal use. |
|
||
| **Basic (regular), \$6/mo — recommended** | 1 | 1 GB | More headroom, still gets an automatic swapfile |
|
||
| Basic (regular), \$12/mo | 1 | 2 GB | Comfortable — no swap needed, a handful of concurrent calls |
|
||
| Basic (regular), \$24/mo | 2 | 4 GB | Several simultaneous calls, conference bridges, transcoding |
|
||
|
||
10 GB SSD (the \$4/mo plan's disk) is enough — this stack isn't storage-heavy,
|
||
and the swapfile only takes 2GB of it. Any DO region close to where the
|
||
phones actually are is fine; SIP/RTP care about latency more than raw
|
||
bandwidth.
|
||
|
||
**Swap:** DigitalOcean doesn't provision swap by default, and Docker +
|
||
Asterisk + coturn leave little headroom at 512MB–1GB RAM. This installer
|
||
detects RAM ≤2GB with no existing swap and offers to add a 2GB swapfile
|
||
automatically (persisted in \`/etc/fstab\`) — it's what makes the \$4/mo plan
|
||
viable instead of risking an OOM kill under load.
|
||
|
||
**OS image:** Ubuntu 24.04 LTS (supported through April 2029) is the safe,
|
||
battle-tested choice for Docker + coturn. Ubuntu 26.04 LTS is also available
|
||
and supported longer (through 2031) if you'd rather track the newer LTS.
|
||
|
||
## DNS
|
||
|
||
Before running this installer, point an A record at the droplet's public IP:
|
||
|
||
\`\`\`
|
||
sip.yourdomain.com A <droplet public IP>
|
||
\`\`\`
|
||
|
||
The installer reads the droplet's public IP itself (via the DigitalOcean
|
||
metadata service) and shows it to you during setup. This one FQDN is used
|
||
for SIP, the web admin, and the TLS cert — there's no separate domain to
|
||
plan for the admin panel.
|
||
|
||
## Security
|
||
|
||
- **SSH:** key-based auth only, password login disabled — \`services/base.sh\`
|
||
in this repo offers to do this for you on first run. Don't skip it; this
|
||
box is public.
|
||
- **Two firewall layers, same rule set:**
|
||
- **DigitalOcean Cloud Firewall** — filters at the network edge, before
|
||
traffic reaches the droplet. This installer offers to create one
|
||
automatically via \`doctl\` (only if none is already attached to this
|
||
droplet — it never overwrites an existing one, to avoid clobbering a
|
||
custom SSH allow-list). If \`doctl\` isn't set up, add the rules below
|
||
manually in the DO console (Networking → Firewalls).
|
||
- **UFW** — host-level, configured automatically by this installer as a
|
||
second layer. Keep both in sync; don't let them contradict each other.
|
||
- **CrowdSec** — SIP brute-force/enumeration protection (\`crowdsecurity/asterisk\`
|
||
collection). Not installed by this script — install it separately (whiptail
|
||
menu, or \`sudo ./setup.sh crowdsec\`); its own installer auto-detects this
|
||
asterisk-digital-ocean install and wires up SIP protection regardless of install order.
|
||
- DO's paid Droplet Backups, or \`services/borg-backup.sh\` installed
|
||
separately, are both options for a rollback path.
|
||
|
||
### Ports (open on both the Cloud Firewall and UFW)
|
||
|
||
| Port | Protocol | Purpose |
|
||
|---------------|----------|-----------------------------------|
|
||
| 22 | TCP | SSH (keep this open or you're locked out) |
|
||
| 5060 | UDP/TCP | SIP signalling (unencrypted) |
|
||
| 5061 | TCP | SIP over TLS |
|
||
| ${WEB_ADMIN_PORT_VAL} | TCP | Easy Asterisk web admin (auto-picked — see \`.env\`). Only opened publicly if Caddy isn't fronting it locally — otherwise it's reachable only via \`https://${DOMAIN_NAME:-your-domain}/\`, not the bare IP:port. |
|
||
| 8088/8089 | TCP | Asterisk HTTP/WS (ARI/AMI) |
|
||
| 3478 | UDP/TCP | TURN/STUN (coturn) |
|
||
| 10000–20000 | UDP | RTP media streams |
|
||
| 49152–49252 | UDP | TURN relay media ports |
|
||
|
||
## Other services (installed separately, not by this script)
|
||
|
||
This installer only sets up Asterisk + coturn. Everything else — Caddy,
|
||
CrowdSec, Authelia, ntfy, watchtower, wg-easy, NetBird, Borg backup — is a
|
||
normal service in this repo: pick it from the whiptail menu, or run
|
||
\`sudo ./setup.sh <name>\` directly. A few integrate automatically with this
|
||
install if already present, no extra config needed:
|
||
|
||
- **Caddy** — if installed (locally, or you're on a remote-Caddy setup), this
|
||
installer reverse-proxies the web admin on \`DOMAIN_NAME\` and Asterisk syncs
|
||
the resulting Let's Encrypt cert for SIP-TLS too. Not installed → self-signed
|
||
cert, plain HTTP admin.
|
||
- **Authelia** — if installed locally (needs Caddy), or you point this
|
||
installer at a remote instance (e.g. a homelab, via NetBird mesh IP or a
|
||
public \`https://\` URL), the web admin gets SSO/2FA in front of it.
|
||
- **CrowdSec** — see Security above; wires up SIP protection automatically
|
||
once installed, regardless of whether it went in before or after this.
|
||
|
||
## Manage
|
||
|
||
\`\`\`bash
|
||
docker compose up -d --build # build image and start
|
||
docker compose up -d # start (after initial build)
|
||
docker compose down # stop
|
||
docker compose logs -f # follow logs
|
||
docker compose pull # update coturn image
|
||
docker compose up -d --build # rebuild asterisk image
|
||
\`\`\`
|
||
|
||
## Management script
|
||
|
||
\`\`\`bash
|
||
docker exec -it easy-asterisk-do easy-asterisk --help
|
||
\`\`\`
|
||
|
||
Use it to create SIP extensions (Server Settings → Extensions) before
|
||
connecting a phone.
|
||
|
||
## Connecting with Sipnetic (Android)
|
||
|
||
[Sipnetic](https://www.sipnetic.com/) is a free Android SIP client with
|
||
TLS/SRTP and STUN/TURN/ICE support — a good fit for this setup. (iPhone
|
||
users: Linphone or Zoiper cover the same ground.)
|
||
|
||
1. In the Easy Asterisk web admin, create an extension — note its
|
||
username/number and password.
|
||
2. In Sipnetic, add an account with:
|
||
|
||
| Setting | Value |
|
||
|-------------------|------------------------------------------------|
|
||
| Username | extension number/username from easy-asterisk |
|
||
| Password | extension password from easy-asterisk |
|
||
| Domain | \`${DOMAIN_NAME:-$PUBLIC_IP}\` |
|
||
| Transport | TLS |
|
||
| Port | 5061 |
|
||
| SRTP | Enabled (optional, for encrypted media) |
|
||
| STUN/TURN server | \`${DOMAIN_NAME:-$PUBLIC_IP}:3478\` |
|
||
| TURN username | \`easyasterisk\` (see \`.env\` → \`TURN_USERNAME\`) |
|
||
| TURN password | see \`.env\` → \`TURN_PASSWORD\` |
|
||
|
||
3. Save and let it register. If it registers but calls connect with no
|
||
audio, double-check the RTP/TURN port ranges are open on *both* firewall
|
||
layers above.
|
||
|
||
## TLS certificate
|
||
|
||
Caddy is what actually talks to Let's Encrypt — Asterisk never does ACME
|
||
itself. The installer always reverse-proxies the web admin on the exact
|
||
same FQDN used for SIP (never a separate "admin" domain), specifically
|
||
because that's what makes Caddy hold a cert matching \`DOMAIN_NAME\`. The
|
||
container then mounts Caddy's cert store read-only and the entrypoint syncs
|
||
that cert in automatically on every start — and re-checks every 12h so
|
||
renewals get picked up without a restart. No Caddy on the box, or no FQDN
|
||
set at all, falls back to a self-signed cert (phones must be configured to
|
||
accept it manually).
|
||
|
||
## Web admin
|
||
|
||
Access the Easy Asterisk web interface at http://<droplet-ip>:${WEB_ADMIN_PORT_VAL}
|
||
or via your configured reverse-proxy domain.
