A word of warning: These greetings will not do you any favors if you're in the midst of a job hunt or work in a conservative industry. Always remember your target personas. If there's a chance they won't appreciate your sense of humor, opt for a straightforward greeting instead.
“Hello ____. This is _____ again, calling from ______. I ran across some information on a client who made dozens of offers on houses before someone finally accepted one of them. We learned a lot from the experienced and I successfully used the findings to help other homebuyers make bids that were accepted early in the house hunting process. I thought I would share it with you in hopes of saving you time and making it easier for you to purchase the home of your dreams. I’ll email you the information. Give me a call if you would like to review it together. Thank you.”

A general voicemail greeting is what callers will be greeted with if you are unable to answer the phone at work. It is the everyday greeting, used as the default, unless you have set up a temporary greeting, such as an away message while you're on vacation, or a special message during a holiday.
12. “Hello, you’ve reached the Customer Support department at [company name]. We are unable to take your call at the moment. We know your time is valuable so instead of placing you on hold, let us call you back! Please leave your name, phone number, the reason for your call, and two different times that are convenient for you to receive a call back from us. Thank you!” Get a better idea of your caller’s schedule by asking them for a few different times you can call back. Their time is important, too!
