Manage Voicemail from an Outside Line

If you need to access your voicemail from your cell phone or some remote location, or you need to change the greeting or such, you can do so easily by dialing into your voicemail as if you were going to leave a message.  While it is playing your greeting, hit the star key and it will prompt you for your password.  After that you get the same menu as you would get accessing the voicemail from your iTel phone.
