This document describes an Interactive Voice Response system using free and open source software that allows schools to send voice messages to parents and students by connecting a computer to a data card and SIM card. The system allows schools to record an audio message on a mobile phone or computer, transfer it to the computer, connect to a data card and SIM, input phone numbers, and use the Swara software to make voice calls to share information and notifications with parents and students quickly and inexpensively. Larger schools may prefer to use an external service provider for higher call volumes.
