With Visual Voicemail on iOS 9 you can listen to a Voicemail easily and you can also save or send a message on to someone else through iMessage or email.
Hello! You have reached the voicemail of John Doe . Please leave your name, phone number, and a brief message and she will return your call as soon as possible. Thank you and have a great day.

Voxist users today benefit from the efficiency of our high-quality transcriptions which allow them to read their voicemail messages in-app or via email. They can also delight their callers with customized greetings which they record using their own voice. Our loyal customer base calls us a “voicemail on steroids” (yup we couldn’t make this up ourselves), but there’s one personalized greeting feature they’ve been requesting us to add since the day we launched….
The very first thing to be checked is, have you set up the voicemail earlier or directly recording the voicemail greeting? If you haven’t already set up the voicemail and unable to record voicemail greeting, then go to the top of the page and learn how to set up voicemail on the iPhone.
