You will probably have to practice it a few times, until your voice is stronger, louder and clearer. That’s your homework now, in case you haven’t got a Voicemail greeting.

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.
In today’s world of digital messaging, email, and text messaging, your business answering machine message might be an afterthought. However, you’d be surprised how many people still prefer to use phones and speak to a person directly or leave a voicemail message that can be returned at a later time.
