How to record phone calls on iPhone
1) Call a person on your iPhone.
2) When the call is established, tap Add Call on the Phone app’s screen.
3) Now call the phone number you’re ringing the person from. Because you’re already on the call, ringing your own number will take you straight to your voicemail, which is precisely what we want.
4) After the greeting message has been played and Visual Voicemail has started recording the call, tap the Merge Calls button on the calling screen.
The iPhone will merge your first call with the other one that went to your voicemail, meaning you’re now actually recording the conversation right into your voicemail.
5) End the call and then tap the Voicemail tab within the Phone app and wait until your recorded conversation appears in the interface as a voicemail message.
Tip: Your iPhone must be connected to your carrier’s cellular data network for new voicemails to be downloaded to the device.
6) Tap the recorded conversation and then hit the Share button.
7) Choose if you’d like to wirelessly send the audio file to your Mac via AirDrop, attach it to an iMessage or email message, send it to Notes or shoot the file to one of your favourite apps in iOS’s multi-purpose Share menu, like Dropbox.
