1. Access your digital voice mailbox through your smartphone's touch screen. On an iOS phone, tap on the Phone application and then look for a square in the bottom right hand corner of the screen that reads Voicemail. Tap this button and your voice messages will appear on the screen. Click on any of the messages and press Play to hear the message. On an Android phone, a voicemail icon will appear at the top left of your screen in the Status area if you have an unread voicemail. Swipe your finger down from the top of the screen to view your notifications and then press New Voicemail. Your phone will dial the voice mailbox.
4. Voicemail greetings for calls received after business hours. You don’t want to answer calls 24/7 (unless you’re serving clients globally and there’s an expectation of 24/7 support).

The process of using a voicemail greeting recorded by a professional voice talent is somewhat easier. You'll still want to review your current message and write your script, but you can submit your script to be recorded and edited and upload the file to your phone system when it's finished.
Hi, we aren’t in at the moment, if you are trying to sell us something please start speaking now and hang up at the beep, everyone else start speaking at the beep and hang up when you’ve finished.
