One Call Now is America’s largest message notification provider. More than 35,000 clients— schools, businesses, hospitals, first responders, churches and communities—depend on them for day-to-day and emergency notifications. One Call Now uses cloud computing technology, so message initiation requires no software purchase or installation. Other notification providers use hardware dialers—housed at your facility—for day-to-day phone calls and use web-based notification only for emergencies. One Call Now makes it easy for administrators and departments to quickly communicate to students, staff and parents via voice, text and email… and get results!
