A secretary in a doctor’s office creates a voicemail greeting that says, “If you have a scheduled meeting with us, we could use copies of all your medical documents from last year, so come prepared.” Using the word “could” gives patients the impression that they don’t necessarily “need” last year’s documents. See the difference between “could” and “need”? Your word choice can impact a future meeting significantly. If you want a customer to perform a specific action, you need to pay close attention to how you express your calls-to-action.
6. Write It Out And Rehearse. Unless you’re part of the 1% of people who love and excel at public speaking, you probably have a hard time conveying an unscripted message without a few pauses and 'um's here and there.

Some of the Quickstart code wasn’t necessary for our IoT Podcast voicemail. The first section of code highlighted in the above image, for example, is used to identify callers for a customized greeting, but only if you know the caller’s number in advance. So I removed that. Additionally, there’s a section of code that reads aloud text for the voicemail greeting. We decided to record our own MP3 file for the greeting, so I modified that line as well. You can tweak the sample code however you’d like if you decide to create a similar project.
