We actually know a top insurance sales guy who did a sales motivational message every day just like this, and people used to call just to listen to his thoughts.
Can’t thank you enough!!!! I’ve been living without my voicemail for about a month, putting off fixing it or finding someone who can. Decided to Google it, found your fix it page and in under 5 minutes it’s fixed!!!

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.
