Google Voice provides free voice mail, free phone number and conversation recording.

When you answer calls made to your Google Voice number, tap 4 on the Phone app's number pad. Participants will hear a robot voice state that recording has begun—this is Google's way of keeping you legal, as Alphabet Inc. wants no part of a lawsuit. To stop recording, tap 4 again or hang up. You can hit the 4 key as often as you like in a conversation to start and stop recording.

"Incoming call options" must be activated in the Google Voice settings, which you can reach via the hamburger menu () in the mobile app or via voice.google.com on the desktop.
