Input Node

The Input module collects multi-digit keypad choices (DTMF) pressed by users, bridging call routing based on numeric inputs.

Configuration Guidelines

1. Timeout Fallbacks

Always map the secondary Timeout connection port to an apology block to prevent lost callers from getting stuck.

2. Termination Key Customization

Set specific finish characters (e.g., # key) to conclude string parsing instantaneously.
