Call Recorder is one of the most popular voice recording applications. It also records phone calls. However, it is not great for general use.
The application presents recording of incoming and outgoing calls, playback options, white and black lists, and more. You can even set your source to be a microphone, a voice call or a video camera. The free version contains advertising, while the pro version does not. Otherwise, both versions should work more or less the same.
