Updating, backups and monitoring

Updating SelfPhoneNG

SelfPhoneNG runs in Docker only. Each release has container images (selfphoneng-api and selfphoneng-asterisk) and an entry in the changelog. Read the entries between your version and the new one first: anything you must do by hand, such as a new setting for .env or the stack, is listed there under the version that needs it.

You don't run database upgrades yourself. When a new version starts and its database changes haven't run yet, the api backs up first (into the backups folder, without recordings), then makes the changes. If that backup fails (the backups folder is missing, read-only or full), the api stops and leaves the database as it was, so the old version still works: fix the cause and start it again. Only if you must update right away, set SKIP_BACKUP_BEFORE_MIGRATE=true for the api, start it, and remove the setting afterwards.

Updates restart the api and Asterisk, which drops calls in progress. Pick a quiet time.

Installed with scripts/install.sh (docker compose)

cd selfphoneng
sudo scripts/update.sh            # the newest release; or e.g. scripts/update.sh v0.0.3

The script:

1. Checks: Docker, that no files in the folder were changed, at least 3 GB free, and no calls in progress. It shows the changelog and any new .env settings, then asks before going on (--yes doesn't ask; --force goes on despite calls in progress, low disk space or a failed backup).
2. Backs up (database, voicemail, custom sounds and music on hold) and compacts Asterisk's logs (gzipped, kept 90 days).
3. Builds the new images while the old version keeps running, then restarts.
4. Checks that the api answers with the new version, Asterisk has started, and every trunk that was registered still is.
5. If the check fails, it goes back to the old version by itself, restoring the backup when the database was already changed.

Each run is logged in data/update-logs/, with one line per update in data/update-logs/history.

A folder from before the script existed (v0.0.2 and older) gets it with the release: run git fetch --tags && git checkout v0.0.3 first (with the release you want), then sudo scripts/update.sh v0.0.3. The running version stays up until the script restarts it.

Portainer, or another setup with pulled images

1. Settings → Backups → Back up now, and download the backup.
2. Change both image tags to the new version (for example selfphoneng-api:0.0.3 and selfphoneng-asterisk:0.0.3), and add any new settings the changelog lists.
3. Redeploy the stack (in Portainer: Update the stack, with Re-pull image on).
4. Check: System (or About) shows the new version; trunks show Registered; make a test call.

Use exact version tags such as 0.0.3, not latest, so you choose when to update.

Going back: an older version can't always run on a database a newer one changed, so going back means the old tags and a backup from before the update: the one from step 1, or the one the api made before changing the database. scripts/restore.sh is for compose installs; with a stack, restore by hand. The stack's APP_SECRET must be the one the backup was made with.

1. Put the old tags back, and stop the api and Asterisk containers (Postgres keeps running).

2. Replace the database (<postgres> is your Postgres container's name):

   docker exec <postgres> psql -U selfphoneng -d postgres \
     -c 'DROP DATABASE IF EXISTS selfphoneng WITH (FORCE)' -c 'CREATE DATABASE selfphoneng OWNER selfphoneng'
   tar -xzOf selfphoneng-20261021-0300.tar.gz db.sql | docker exec -i <postgres> psql -q -U selfphoneng -d selfphoneng
   

3. Replace the folders the backup has (tar -tzf lists them: voicemail, sounds-custom, moh, maybe recordings) in your data folder, and give them back to the app user: tar -xzf selfphoneng-….tar.gz -C <data folder> voicemail sounds-custom moh after removing the old ones, then chown -R 1000:1000 them.

4. Start Asterisk and the api. The api rebuilds Asterisk's config from the restored database.

Asterisk security releases

SelfPhoneNG builds Asterisk from source, checking the download against Asterisk's published checksum. New Asterisk versions come with SelfPhoneNG updates.

To take an Asterisk fix before that, build the version you need yourself. Release numbers are listed at https://downloads.asterisk.org/pub/telephony/asterisk/releases/.

docker compose build --build-arg ASTERISK_VERSION=24.0.1 asterisk
docker compose up -d asterisk
docker compose exec asterisk asterisk -rx "core show version"

A later rebuild without --build-arg goes back to the version the code names.

Backups

Settings → Backups:

• Back up every day at a time you choose, keeping the newest few.
• Back up now makes one right away.
• The list downloads any of them.

A backup (data/backups/selfphoneng-YYYYMMDD-HHMMSS.tar.gz) holds:

• the database: users, extensions, numbers, settings, call history;
• voicemail;
• your sounds and music on hold;
• call recordings, if you tick "Include call recordings" (they can be large).

If a daily backup fails, the admins get an email, and the dashboard warns while today's backup is missing.

Two things a backup doesn't hold:

1. .env. Its APP_SECRET encrypts the SIP and trunk passwords inside the backup.
   • A backup can only be restored with the .env it was made with, so keep a copy of .env in a password manager.
   • The backup itself holds no plain passwords.
2. A copy anywhere else. Backups sit on the same disk as the system. Copy them off the server regularly, e.g. with a nightly cron job: rsync -a /opt/selfphoneng/data/backups/ backup-host:selfphoneng/.

Restoring

./scripts/restore.sh /path/to/selfphoneng-20261019-0300.tar.gz

The script:

• refuses if .env's APP_SECRET isn't the one the backup was made with;
• shows what the backup holds and asks you to type yes;
• replaces the database and those folders, then starts everything again.

Asterisk's config is rebuilt from the restored database. Sign in with the passwords from the backup.

Moving to a new server

1. Clone SelfPhoneNG on the new server.
2. Copy your old .env into the folder.
3. Run ./scripts/install.sh. It keeps the existing .env.
4. Run ./scripts/restore.sh <backup>.
5. If the public IP changed: update it on Settings → Network, change your DNS record and any IP-based settings at voip.ms (IP authentication, API whitelist), then docker compose restart asterisk.
6. Desk phones fetch their setup from the host name, so they follow the DNS change.

Monitoring

Emails to admins. SelfPhoneNG emails every admin when:

• a trunk has been down for 5 minutes (one email per outage);
• the disk is under 10% free (once a day);
• the public IP changed (with the re-check turned on);
• a daily backup failed.

These need Settings → Email working.

Health check for an uptime monitor (Uptime Kuma or similar), on the server itself:

curl http://127.0.0.1:8080/healthz      # 200 {"ok":true}, or 503 when the database is down

From outside, monitor https://pbx.example.com/healthz.

The dashboard shows trunks, active calls, queues and warnings (emergency setup, certificate, backups, restart needed) live. System has the event log: trunks going down and back up, Asterisk stopping and coming back, restarts needed, 911 calls, public IP changes, backups and a full disk, kept 90 days (Download saves it as CSV).

Keeping logs small

Asterisk's log files in data/asterisk-logs/ grow forever. Rotate them with logrotate. Create /etc/logrotate.d/selfphoneng:

/opt/selfphoneng/data/asterisk-logs/*.log {
    weekly
    rotate 8
    compress
    delaycompress
    missingok
    notifempty
    copytruncate
}

copytruncate lets Asterisk keep writing to the same file. fail2ban and CrowdSec notice the file shrinking.

scripts/update.sh also compacts them on every update (gzipped next to the log, kept 90 days).

The api's logs are Docker's. docker-compose.yml keeps three files of 10 MB per container. In a Portainer stack, add the same to each service:

    logging:
      driver: json-file
      options: { max-size: 10m, max-file: '3' }

Or set it for every container in /etc/docker/daemon.json with "log-opts": {"max-size": "20m", "max-file": "5"}, restart Docker, then recreate the containers (the limit only applies to new ones).
