Use a Third-Party Record a Call on an iPhone
One of the easiest ways to record a call on an iPhone is by using a third-party app. Since Apple does not provide a built-in call recorder, apps such as Rev Call Recorder, TapeACall, and Call Recorder – IntCall can help. Another trick to record a call on an iPhone is by using voicemail. Some carriers allow call merging, which lets you record a conversation by sending it to your voicemail.
