Friends and colleagues speak to each using first names only. So do people of authority. They do not call each other and leave voicemail messages asking for Mister, Miss, or Mrs. Therefore, when you call a person you want to do business with and you leave a voicemail message, refer to them by their first name only. Don't say mister, miss, or misses. Don't say their last name. Begin your voicemail message by saying only "hi/hello" followed by the person's first name. Or, you can even forget the "hi/hello" and just say the person's first name. That is how you show confidence and authority and separate yourself from weak salespeople.
This can position you as an expert, make them want to call you back to at least get information, and generate interest in what you do.

If you can get your voice mail greeting professionally recorded, then definitely consider it! These greetings sound great and can have a strong “corporate” or “important” feeling to them. When they are done properly, these recordings can be very memorable and get a lot of attention. A professional voice talent can be hired to make your greeting sound fantastic. Yes, they might be less personal, but they are certainly professional. So it’s up to you which image you want to portray. If you use a web-based voice mail system like Solaxis, then you can upload these recordings directly into your voice mail system.
These work voicemail greetings are for the work phone that you and only you use. They’re highly effective because they help you establish a relationship straight from the voicemail. Or they help you share an important update in a simple, straightforward way.
