Absolutely, I can assist you with that. To simulate your assistant being busy and test the fallback destination, you would typically need to configure your system to recognize a test call as exceeding the concurrency limit. This might involve setting up a test scenario where you make enough simultaneous calls to reach the limit, or temporarily lowering the concurrency limit for the purpose of the test.
If you have access to the system settings, you can adjust the concurrency limit to 1 and then make two calls to see the fallback in action. If you need specific instructions on how to do this, or if you want me to initiate a test call for you, please provide me with the necessary details or permissions to proceed.
