An alltime classic technique was offered by Thomas J. Elijah, III, of Elijah & Co. Real Estate, at a SalesMasters meeting. He said to leave a partial message that includes your name and phone number, then pretend to get cut off in midsentence, as you’re getting to the important part of the message. “Cut it off in midword,” Elijah says, “it works like a charm because the prospect can’t stand not knowing the rest of the information, or thinks his voice mail is broken.”
Follow that with an email that says the same thing, log the call / update your notes in your CRM and MOVE ON!

End your voicemail by asking your prospect to tell you more, whether about their recent vacation to Thailand or their unique business pain points. It's a simple request -- and easier than, say, "Give me a call back, I'd love to find out when we can write up our contract."
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. How do I check my voice mail? To call your voicemail on an Android phone, simply open your phone’s dial pad and hold your finger down on the “1” key. You can also call your voicemail from a different phone by calling your own number and tapping the pound key. How do you listen to voicemail on this phone?
