Caution

Support for v20 and above is experimental and may not work as expected. Please report any issues you encounter. Currently, only monitoring of extensions is supported. Monitoring of groups is not supported due to limitations of the 3CX permissions model.

3cx-zammad-bridge

Monitors calls in 3CX and communicates this to Zammad accordingly.

Requirements

• Linux x86_64

Installation

• Download the latest release binary from releases.
  • Copy the binary into /usr/local/bin
• chmod +x zammadbridge

Configuration

All configuration is done through the config.yaml file, that may appear in these locations:

• /etc/3cx-zammad-bridge/config.yaml
• /opt/3cx-zammad-bridge/config.yaml
• config.yaml (within the working directory of this 3cx bridge process)

The first (found) configuration file will be used. Also refer to the config.yaml.dist file.

For 3CX versions 20 and above, it's important that you create a client ID and secret in the 3CX web interface. You have to add all extensions that you want to monitor to the Call Control API permissions in the 3CX web interface for the client ID you create. Note that monitoring groups this way is not supported (due to limitations of the 3CX permissions model). You have to add all extensions manually.

Example configuration:

Bridge:
  poll_interval: 0.5 # decimal; The number of seconds to wait in between polling 3CX for calls

3CX:
    # For versions below v20, define these two:
    user: "the username of a 3CX admin account"
    pass: "the password of a 3CX admin account"
    group: "the name of the 3CX group that should be monitored, for example Support"
    # For versions v20 and above, define these two:
    client_id: "the client ID you created in 'Admin' -> 'Integrations' -> 'API'"
    client_secret: "the secret that was shown once"
    # Always define these:
    host: "the URL of your 3CX server, including https://"
    extension_digits: 3 # numeric; How many digits the internal extensions have 
    trunk_digits: 5 # numeric; How many digits the numbers in the trunk have
    queue_extension: 816 # numeric; The number of the queue that the bridge should also listen to
    country_prefix: 49 # numeric; optional; The country dialing prefix to remove from the numbers

Zammad:
    endpoint: https://zammad.example.com/api/v1/cti/secret # The URL of your Zammad server, including the secret in the URL
    log_missed_queue_calls: true # boolean; Whether or not you want to log missed calls to your queue

Running

Run the release binary to run the daemon.

Example supervisord config:

[program:3cx-zammad-bridge]
command = /usr/local/bin/zammadbridge
autostart = true
autorestart = true
startretries = 10
stderr_logfile = /var/log/3cx-zammad-bridge.err.log
stdout_logfile = /var/log/3cx-zammad-bridge.out.log

# Optionally specify a user
user = zammad-bridge

Example systemd service:

[Unit]
Description=3cx-zammad-bridge
After=network.target

# If running on the same machine as 3CX, you might want to wait for it to start
PartOf=3CXGatewayService.service

[Service]
User=zammad-bridge
Group=zammad-bridge
ExecStart=/usr/local/bin/zammadbridge
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

Help

3cx-zammad-bridge is a bridge that listens on 3cx to forward information to zammad

Usage:
  zammadbridge [flags]

Flags:
  -h, --help                help for zammadbridge
  -f, --log-format string   log format: "json" or "plain" (default "json")
      --trace               trace output, super verbose
  -v, --verbose             verbose output

Development

You can build the binary by running make build

Theoretically, this should also run on Windows. You can compile it yourself and report possible issues.
