Asus India — LTE not supported

Address: 695582

I am Asus Zenfone 2 user and I have reliance Jio sim but I doesn't support the VoLTE I asked to reliance they said company will give an update to support theVo LTE.
Please assist me to activate the VoLTE system at my mail I also check for the updates or any other available software of the Asus but there is no software to configure 4G sim in device . The reliance Jio voice is inbuilt app is also having problem to configure the VoLTE system only on Asus Zenfone 2 laser handset. So please assist me to configure the reliance Jio sim or provide update . Because my calling is not working and I'm suffering lots of problem.
Thank you.
