Select the Messages tab on the Call History pane.
Double click on the Voicemail box you would like to access (this will either be your personal Voicemail box or the Voicemail box for the Hunt Group of which you are a member) or Right click and select Call Voicemail.
If the phone is On-Hook it will ring once the Voicemail Server has been contacted. Pick up the phone and listen to your messages. Depending on how your telephone had been configured the speakerphone may automatically come on.
If you are using Phone Manager Pro with Voicemail Pro in IP Office or Intuity mode you can use the voicemail control buttons to navigate through the messages.
If the phone is already in the Off-Hook state you will be connected to the Voicemail server as soon as it is located.
