Muzak's on hold message systems are compatible with 99% of phone systems currently on the market and in use. Integration of on-hold phone systems is typically a simple "plug-and-play" process. Most messaging on-hold system set-ups require only the connection of 2 wires, a power cord and an audio cord. Simple as that.
