I don’t think recording and hacking are equivalent.

Recording is a passive act that entirely takes place entirely within the territory of the person doing the recording.

Whereas hacking involves accessing a computer system that is in a different jurisdiction, which necessarily involves actively communicating with it and sending it commands.

Recording a call is more like listening to a radio station. Countries may make it illegal to listen to certain communications, but as soon as those radio waves leave that jurisdiction then they are fair game for anyone who wants to listen to them.

Pretty much everybody should be cautious about entering the US!
