Once you identify your pain points, you’ll find it much easier to identify what instructions need to be present in your voicemail greetings. We hinted towards these before, so let’s just break down another example. If you want your customers to leave a voicemail, but you also want them to visit your website for additional help regarding their issue, give them a clear call to action, like a website address they can easily write down while they listen to your message.
Simply speak into your phone or computer while recording a greeting with your business phone service. If you need to create your own audio file, the voice memo app on your phone should do fine.

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.
