Interactive Voice Response (IVR) is an automated telephony system that interacts with callers, gathers information and routes calls to the appropriate recipient or does an already defined activity on call like playing audio files. We have configured on demand IVR system for the people associated with DSS so that they can connect using a short code provided by various operators and listen to Live or recorded satsang audios.
