If you are recording a voicemail message for business, be sure you include your name and your company’s name, so people know who they are calling and were they are reaching them. If you do not include the business name, they may think they have mistakenly called you at your personal number. Step One: Introduction. Start with an upbeat greeting that includes the name of the person you’re calling: “Hi, Tim!” “Hello, Susan!” “Good morning, Tom!” Then, introduce yourself by giving your name, company name if applicable, and telephone number. Step Two: Message. Step Three: Recap and sign off. What is a professional voicemail greeting?
Of course, yours may need more details. But, even if you’re changing your outgoing message every day, it should only be a slight variation from a standard greeting.

Android phones can access voicemail by holding down the 1 key on the dial pad until the phone dials your 10-digit phone number. You will automatically connect to your mailbox and be prompted to enter your temporary password; this password is the last 4 digits of your phone number followed by the # key.
