Whenever a new technology comes it provides better user experience. Since the role out of a new technology requires a lot of money investment. It makes services expensive for users. For what reasons an operator would like to deploy VoLTE when it is already have Circuit switch fall back for voice services. In India, Reliance Jio is a new player in telecom market that's why it is rolled out VoLTE since it was not having any legacy technology to provide voice services. What about others ? Are they deploying VoLTE just for the namesake that they also support VoLTE or really there is a need for that ?
