I am upgrading my system to a Partner ACS v5 with Messaging R 1.0. I would like to add a very good "music on hold" digital player that I can load from a CD or other high quality source. I am not really interested in AM / FM since I am in a remote location without any quality radio stations. Is it possible to play out of memory and reload automatically in the event of power failure? Does anyone have any experience with this type of device?
