My 4G mobile is absent in Jio VoLTE support list !
No problem, You can either contact mobile vendor via Chat or support mail or keep eyes this page for further details on volte supported mobile phones. Most of Android phone with Qualcomm CPU ranging from 410 to 820 support VoLTE and they need an update from operator to fully process voice calls using VoLTE service.

May require to update to MM to get VoLTE.
Already upgraded to MM. Current Version 6.0 Software Version - V20c-IND-XX
i have had a discussion jointly with Jio and LG support team it is jio who needs to support the handset. i.e jio needs to roll out operator update so that LG g4 gets VOLTE.
i have used LG G4 H818N n hong kong on china mobile and VOLTE works fine there.
Any update regarding this? I recently got Jio 4G SIM on my H818N Indian model. LTE and incoming SMS are working fine but I cannot make or receive any calls or send SMS.
I do have LG g4 h818n Indian version with LTE. Recently got JIO sim bit it has not activated. I am worries does my mobile support VoLTE or not. Even there is not article found how to enable VoLTE to LG G4 indian version. Please let me know if anybody has idea of it.
No volte works on lg g4 now and there is no say to activate it.iam using jio for calls use jiojoin.waiting for a software update by lg which activate volte.

https://forum.xda-developers.com/lg-g3/general/refurbished-fake-lg-g3-check-available-t3254928
Turns out my mob is orignal but its software is changed
According to the Software Ver of Mobile it says : KVT49L.D85510o
But In boot menu it says : KVT49L.LS990zv4
