You can set the greeting tone as per your own choice, which would be much interesting. Sometimes we get to hear boring voicemail messages which are not inviting at all to leave behind a message. This happens more frequently in business dealings. To avoid such responses, we have presented you samples of cool voicemail greetings.
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.

Note: I have several lessons about communicating on the telephone that may be useful to you:
Be brief. Don’t make your listener resent you for leaving a 5 minute long message. People are busy. Listening to 5 minute phone messages is not on the top of their priorities and wastes their time. Many callers seem to think they are the only person in the world leaving a voicemail for a particular person. Yet a dozen other people feel the same way and a man ends up holding the phone to his ear for an hour.
