With the latest iOS updates, it's easy to record call on iPhone. To record a call, simply initiate or answer a call, then click on the "More" button and choose to record the call. Once you do this, the other person is informed that the call is being recorded. It will continue to record until you turn off recording or end the call. It will then be automatically saved in the Notes app, where you can listen to the file, read the transcript, and view key details at any time.
