5. Hit “Record” on Audacity. Then, on your phone, play the voicemail you’d like to record. When your message is done, stop recording. If you want to get really fancy, you can use Audacity to chop off any dead air at the start or end of your recording.
With this in mind, here’s how to configure Voicemail and Visual Voicemail on Samsung Galaxy devices:

12. “Hello, you’ve reached the Customer Support department at [company name]. We are unable to take your call at the moment. We know your time is valuable so instead of placing you on hold, let us call you back! Please leave your name, phone number, the reason for your call, and two different times that are convenient for you to receive a call back from us. Thank you!” Get a better idea of your caller’s schedule by asking them for a few different times you can call back. Their time is important, too!
With this method, you don’t need a third-party app. Call the person you want to chat with, then tap the “Add Call” button on your phone’s screen. Dial your own phone number—the one you’re calling from. This will take you to your voicemail. Once your voicemail has started recording, tap the “Merge Calls” button on your screen. Now, you’ll record your phone conversation onto a voicemail message. When you’re done with the call, you can tap the share button to export it to your Mac via Airdrop, to the Voice Memos app, or transfer it via email or text message. The file is recorded as an M4A, so depending on what you want to do with it, you may need to convert it to MP3 before uploading it to other apps.
