Recording Phone Calls on an iPhone Without Using Apps This method can be considered as the easiest, fastest, and perhaps “dirtiest” way of recording a phone call from an iPhone. All you basically need to make this work is another device that has a microphone that can record (like a computer, iPad, or a portable recording device).
The telephone systems have the feature named as Voicemail. VoIP is the best example of it. When a receiver is unable to pick up the phone, then the caller can leave the voice message on the receiver’s phone. In older telephonic machines, such messages were stored as a voice message directly, and the receiver can hear them later. In modern telephone systems, such info is being stored on the server of the service provider in the user’s mailbox. It is similar to email in which the messages are saved in the form of audio instead of text.
