I do work for a US company from outside the US and if I can't identify the people I'm talking to I have to hang up. We have yearly training on the importance of not sharing internals if not authorized. In that case I'd ask them for the full name so I can look them up and call them back. But I also wouldn't be scared of getting fired for that, quite the opposite I'd also happily resign if they ask me to talk to random people about internals.
