It can be done by asking some obvious question for humans:
"This is a anti-robocall system, please answer the question to complete the call. A mother cat and her three kittens are sleeping in a box. Dial the number of animals in that box."
The number of kittens change randomly and maybe the system can put some pillows, blankets and other non-animals in the box too, making automated processing harder. AI will get there, sure, but this will make things expensive for the attackers.
Of course this assumes enough people follow the pattern of press some number to continue. Every time the pattern changes the cost of understanding it and fitting it into their system goes up. In the end though it isn't a scheme we can win: AI can successfully follow more complex processes than humans can in this limited space - including random failure to follow the instructed process if it is too complex.
