Jazzd Phone will make sure you never miss a call, so you’ll never be inconvenienced, even if your Internet connection fails. Your calls will automatically be forwarded to your Voice Mail in the event your Internet connection is disrupted or your terminal adapter is disconnected. As soon as your Internet connection is restored, you'll hear a stutter dialtone, when you pick up your handset, that will indicate that you have messages in your voice mailbox.
