Overview

This node interacts with the Asterisk PBX system via the Asterisk REST Interface (ARI). Specifically, the 'Set Variable' operation under the 'Asterisk' resource allows users to set a global variable within the Asterisk system. This is useful for managing and controlling call flows or system behavior dynamically by updating global variables during runtime.

Use Case Examples

1. Setting a global variable to track call status or user preferences.
2. Updating system-wide flags or counters used in call routing logic.

Properties

Output

JSON

• variable - The name of the global variable that was set.
• value - The value assigned to the global variable.

Dependencies

• Requires an API key credential for authenticating with the Asterisk REST Interface (ARI).

Troubleshooting

• Ensure the API credentials are correctly configured and have sufficient permissions to set global variables in Asterisk.
• Verify that the variable name is valid and does not conflict with existing system variables.
• Check network connectivity to the Asterisk ARI endpoint specified in the credentials.
• Common error messages may include authentication failures, permission denied, or invalid variable names. Resolving these typically involves verifying credentials, permissions, and input values.
