To hang up a phone call from the US, you can follow the same procedure as you would in any other country. Here are the steps in English:
1、Say "Goodbye" or "Thank you, goodbye" to the caller.
2、Press the hang-up button on your phone (usually a button with a red phone icon on it).
3、If you are using a mobile phone, you can also simply tap the "End Call" or "Hang Up" button on the screen.
Remember to use polite language when disconnecting the call, as it is customary in most countries to show courtesy to the caller even when ending the call.
