How is an Auto Attendant tested during an Avaya IP Office installation?

Testing an Auto Attendant during an Avaya IP Office installation is done by creating and dialing a new Auto Attendant Short Code. To successfully test the functionality of the Auto Attendant, it's important to ensure that the configured Short Code is correctly set up to route calls through the Auto Attendant features you've implemented. By dialing this Short Code, users can confirm that the Auto Attendant is responding as expected—providing options or directing calls correctly according to the programmed settings.

The other options involve codes related to voicemail rather than directly testing the Auto Attendant. While voicemail features are integral to the overall telephony system, they do not serve the purpose of validating the specific settings and operation of an Auto Attendant. Therefore, using a dedicated Short Code for the Auto Attendant is the best way to confirm that it is functioning correctly.
