Asterisk Media Support

For Asterisk media support, you can use a custom YAML configuration file. The agent includes default handlers for Asterisk that can be customized via YAML.

Default Asterisk Handlers

The agent provides built-in handlers for Asterisk:

1. Hangup Handler - Handles hangup actions
2. Listen Handler - Handles audio stream start actions (with break: true to stop further processing)

Custom YAML Configuration

Create a custom YAML file (e.g., asterisk.yml) to customize Asterisk handlers:

executor:
  listen:
    type: softswitch-interface
    only_for: "asterisk"
    break: true
    when:
      action: start
      app_id: audio
    command: Originate
    interface:
      Channel: PJSIP/<OUTBOUND ENDPOINT>/sip:voipstack@${VOIPSTACK_GLOBAL_AGENT_MEDIA_SIP_HOST}:${VOIPSTACK_GLOBAL_AGENT_MEDIA_SIP_PORT}
      Application: ChanSpy
      Data: ${VOIPSTACK_ACTION_VENDOR_CHANNEL},q
      Variable: "PJSIP_HEADER(add,X-VOIPSTACK-STREAM-IN-URL)=${VOIPSTACK_ACTION_INPUT_INPUT_STREAM_IN_URL}"
      Async: true

Running with Custom YAML

./voipstack_agent -s asterisk://ClueCon:ClueCon@ip -c /path/to/asterisk.yml

Environment Variables for Asterisk

The following environment variables are available for customization:

• VOIPSTACK_AGENT_MEDIA_SIP_HOST - Media SIP host (default: 127.0.0.1)
• VOIPSTACK_AGENT_MEDIA_SIP_PORT - Media SIP port (default: 6070)

Example Asterisk Configuration
