If you receive a call from the US and the caller doesnt say anything, you can handle it in English as follows:
Hello, who’s this? I didn’t hear anything you said. Please speak up or leave a message. If you don’t want to talk to me, I can just let the call ring through.
这段话的意思是：你好，请问你是哪位？我没听到你说什么，请大声说话或者留下信息，如果你们不想和我说话，那我就让电话响着好了。
