Your screening rules decide who reaches a licensed agent, so on the Good Fronter tiers VoiceOI doesn't leave the age rule to the AI alone.
Callers answer in their own words, and the bot works out the value it needs: "72", "seventy-two" and "I was born in 1954" all count as an age. Before a transfer goes through, ranged rules such as your age limits are checked again in code against what the caller actually said. If that check fails, the caller is not transferred on that answer.
This age and ZIP verification is part of the Good Fronter tiers, from $35 per bot per month; the Simple Fronter tiers handle basic filtering only. On any tier, you can keep bots inside the states where your agents are licensed by filtering the list by state, area code or ZIP before dialing.
