IVRS using FreeSwitch PBX

To retrieve relevant information on a mobile phone without having to open up a web browser is not only easier but also efficient in time-constraint situations. To achieve this, we implemented an Interactive Voice Response System (IVRS) for SIP-based phones. This book aims to propose a cost-effective IVR system using a simple PC without having to set up a physical PBX. Telecommunication services play an important role in exchange of information and communication. Although this system is limited to SIP-based phones, in this book we propose a general IVRS that can be implemented for a regular network operated mobile phone and various architectures that can be implemented through our model. This works in favour of institutes and small-scale companies who wish to implement a help line without the use of a physical PBX.
