Overview

This node interacts with the Asterisk PBX system via the Asterisk REST Interface (ARI). Specifically, the 'Get Variable' operation retrieves the value of a global variable from the Asterisk system. This is useful for scenarios where you need to access or monitor system-wide variables within Asterisk, such as configuration flags or status indicators, to integrate or automate telephony workflows.

Use Case Examples

1. Retrieve the value of a global variable named 'CALLERID' to use in call routing logic.
2. Check the status of a system-wide feature flag stored as a global variable before executing a specific telephony action.

Properties

Output

JSON

• variableName - The name of the global variable requested.
• variableValue - The value of the requested global variable retrieved from Asterisk.

Dependencies

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

Troubleshooting

• Ensure the provided variable name exists in the Asterisk system; otherwise, the node may return an error or empty result.
• Verify that the API credentials are correct and have sufficient permissions to access global variables via ARI.
• Common error messages may include authentication failures or variable not found errors; check the variable name spelling and API access rights.
