Hello, Forever. The Audio Guest Book Imagine being able to listen to a loved ones message from your wedding, literally forever. We have 7 different colors to choose from and you even have the option of leaving your own greeting as well. Right now, the only way to book one of our phones is to also book a photo booth. We provide the phone, sign and help on site with operating the phone. Usually set up right next to the photo booth to ensure that everyone takes advantage of leaving a message. The voicemails recorded on the phone are all individual MP4 files which can be saved and listened to on any platform. To add an audio phone to your package just let us know.
