The phrase ‘Your call is important to us’ is very overused and can sometimes come off as insincere. Instead your professional voicemail greeting should say something like ‘We appreciate your call and look forward to speaking with you soon.’
I am not a voice talent, and I hate the sound of my own voice. Every time I lose my cell phone (daily), I call it from another line to help myself find it. And every time I do this, I wish my voicemail message sounded…different. I’m always reminded that I should sit down and rerecord it, so it makes a more professional first impression.

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.
A busy greeting should tell callers that your phone lines are currently in use. You can direct people to wait on hold or leave a message. For example, “Hello, you’ve reached [company name]. Our representatives are currently helping other customers. Please stay on the line to speak with the next available team member, or press one to leave a message and we’ll call you back.”
