This is where a professional voicemail greeting is essential for giving the right impression and information; encouraging the caller to leave you a message, and informing you of what you may have missed.
Humor also leaves a lot of room for misinterpretation—which subsequently weakens sincerity and authority. A caller can be very turned off by merely misinterpreting your joke. Why take this risk? Additionally, this could even cause callers to question your character. Say, for example, the president of a company’s mobile phone voicemail greeting was funny. What’s to happen if the caller didn’t like or get the joke? What if they found it offensive? Another scenario is that a caller is reaching out to you for the first time—i.e. they have no idea regarding your personality. What next? The point is, with this type of greeting, humor is bound to be more divisive so just avoid it altogether. c. Poorly Pacing Your Message and Bad Time Management: Don’t speed through your message. Speak clearly so callers know what to include in their message and when to leave the message. At the same time, don’t drag your message out. No one wants to sit through a diatribe. Just get to the point clearly.

If you’re looking for information on [X], please check out our [Facebook page, company website, etc.] If you want to know more about [Y], take a look at [Z page on our site, our YouTube channel, etc.] Still have more questions, or just want to hear our lovely voices? Leave your name and number, and we’ll return your call straight away.”
In both the consumer and business world, it's becoming more common to hear voicemail prompts that warn callers that their messages might not be heard for a while and suggest that they send a text message or email instead.
