If you have subscribed to Voicemail to Text transcription, you can tweet a transcription of a received voice mail.
Follow these steps to tweet a shared voicemail.
1. While in the Message Playback screen, tap the Share menu option. You will be presented with a list of message share types.
Note: This list and its share via Twitter option will appear only if the message being shared was transcribed by the Voicemail-to-Text service. It will not be available otherwise.
2. Select To Twitter.
3. At this point, you may be asked to log into your Twitter account. If this happens, enter your Twitter username (or email address) and password and then tap Sign In.
4. The Visual Voicemail application will display a popup message to confirm that you have successfully tweeted.
