No matter how the call went, always sound professional, friendly, and polite. You don’t have to repeat your message one last time as that’s only wasting precious call time you could’ve spent calling others on your list. Your listener can always replay your message if they want to hear it one more time. End it with a friendly line like, ‘I’m looking forward to hearing from you soon,’ or ‘have a nice day.’
Open your voicemail greeting with a 'Thank you for your call. We're not available right now by please leave your message and we'll get back to you within [specify time]'.

When someone reaches your voicemail, it’s important that you help them confirm that they have reached the right person by providing all of the relevant information that they will need. Who have they reached? Did they contact the right person and the right business? Should they leave a message? When will you get back to them? Is there a better time for them to call?
We’re keeping it simple with this one. Just a few basic elements to help you get started. As long as you know who your audience is, the message you wish to convey, and the information you need from the caller, the rest should fall into place quite nicely. Let’s face it, a voicemail greeting for a lumber company will probably be different than that of a psychologist’s office. One greeting is aimed at securing potential customers, and the other is geared towards appointments, more or less. Once you are certain who your caller is, the better your voicemail. Center on your audience, first and foremost. Knowing what to relate ensures that your caller will leave the right message. For instance, if you’re a retail store, you would include your hours of operations, and perhaps any specials that you’re running. If you are a therapist’s office, then you’d need to include an alternate number in case a patient is having an issue and requires immediate help. Again, this will vary depending on the business. Here, a therapist would definitely request the caller leave their contact information. However, a retail store chain might not request that. There are also complex voicemail systems such as those used by mobile phone services, which ask you to press a certain number on your phone, where you are asked to leave your account information. Again, as you can see, it all boils down to the demographics of your callers, and what you need from them to conduct the best business possible. Depending on the situation, your caller might be in a good mood or not. In either case, they’ll probably be eagerly awaiting your call. So, it stands to reason that you only promise them a call back if you can deliver. In other words, if you’re a small shop and you’ve decided to close due to a much-needed sabbatical, then don’t leave a voicemail greeting where you promise them to call right back. However, if you have an active customer service staff, then you can promise to return their call within the same day.
