dont talk first, let them talk
if they're not talking, they maybe recording your voice
that recording can help them regenerate your voice using AI
so that's the only danger from these scam calls if you dont give any information
also dont let anyone tell you to download any apk or any link in browser that ended with dot apk. those are illegal apps that will monitor your banking apps
its good if you install phone number identifier apps that will let you see what other people named them. sometimes you'll get number that is known by lots as scammer and the apps will tell you the name is scammer
