Asterisk Phone System

Obtain Your Asterisk API URL

• Identify the URL where your Asterisk HTTP API is running (such as http://192.168.4.44:8000).
• If unsure, consult your administrator or hosting provider.

Get the Asterisk API Key

• Obtain the authentication key required to use your Asterisk API.
• This is typically generated in your Asterisk API server’s configuration or admin interface.
• If you do not have this key, ask the administrator who manages your Asterisk installation to provide or generate one.

(Optional) Prepare an MCP Callback URL

• Decide on the callback endpoint for call results (e.g., http://localhost:3000).
• This can be your local MCP client or any endpoint you want call status/results sent to.

Add Environment Variables in FastMCP

• Go to the FastMCP connection interface.
• Click the “Install Now” button to configure the server.
• Enter the values as follows:
  • PHONE_API_URL: Your Asterisk API endpoint (e.g., http://192.168.4.44:8000)
  • PHONE_API_KEY: The authentication key from your Asterisk setup
  • MCP_CALLBACK_URL: Your chosen callback URL

Save and Continue

• Save the configuration in FastMCP. Your connection will use these environment variables to interact with your Asterisk-based conversational calling system.
