AI is absolutely not needed for this, and is only a liability.
They could say "press 1 if you are calling about X" or even "if you are calling about X, we are already aware of it. If not, you will be transferred to an operator in a moment".
An automated system like this is easy to implement, easy to audit, and will fail in expected and managable ways.
AI is nondeterministic, and will fail randomly in very unexpected ways.
It works so well
