There are plenty of third-party apps that use IVR to record phone call conversations in the cloud. And also, they can transcribe the recorded audio files, so you don't need to take notes manually.

Check out the A Call Recorder App, for example (https://acallrecorder.com). This service lets you try recording 60 minutes for free without a subscription! It also can transcribe the recorded conversation.

Tho, it works for USA and Canada only...
