Almost every business phone system that has a "HOLD" button can use this unique marketing service! Most phone systems have a plug (back in the phone room) for "background music" or "MOH". If you can not see it on your main phone system panel, it may be hidden. Please consult your owners manual or ask your phone vendor to help you. Remember, though, if you can currently play a radio over your phone system today, you are ready to go!
