First, I'd like to pay all your closing costs. When you sell your property. To me, this will save you thousands of dollars because normally when you sell your home, I'm just trying to speak to their subconscious mind, sell your property, sell your home, sell your house to me, sell your house to me. It's not overt to them, but I'm being intentional about not just saying that, but subtly emphasizing those embedded commands.
What you do not want to do is say your phone number so quickly that the person has to listen to your voicemail multiple times to try and figure out your phone number. We have all gotten those annoying voicemail messages where the person said their phone number so quickly that we had to listen to their message several times to figure out their phone number. Don't be that jerk who leaves their phone number so fast that the other person has to listen to your message over and over to try and figure out what your phone number is.

Hello… my name is (your name)’s refrigerator. He/she isn’t home right now to take your call. To leave him/her a message, speak very slowly so I can stick the message with the help of these refrigerator magnets.
To set up voice mail, tap the Phone icon, tap the Voicemail icon and then "Greeting.". There are two options available: Default and Custom. If voice mail hasn't been set up previously on your phone, Default is selected, which means people will hear your wireless carrier's generic voice mail greeting when they call you.
