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.
Context does matter here. If the caller would reasonably expect you to answer the phone (such as if they were calling a store or other place of business), an apology for not being able to get to the phone makes the most sense.

There’s no need to complete any extra wiring in a building once internet connections are in place. Additionally, mobile apps and web browser-based phones can just as easily connect to the VoIP network as their desk phone and conference phone counterparts.
The key here is customer service. If it’s information that’ll help your business better serve your customers, don’t be afraid to ask for it. Write out your voicemail script and practice it. It may seem silly, but you’ll save time if you write down what you want to say in your message. Get everything you want to include in your greeting down on paper, and then rehearse it before you record your greeting to ensure your script flows smoothly.
