Yes it's 087. But why mine isn't working ? Are you using the same firmware version ? And please If you find any solution let me know.

Asus already activated VOLTE for this device and works fine with VI sim card.
It might be the SIM/Network provider end issue. You can try to reach VI customer care and ask them to activate volte by mentioning your device company model details. They will activate/ if it not getting then you have to replace with new SIM card from your network provider.
Even if not working, you have to visit nearest Asus service centre to get help with your problem since, device software already supports the VOLTE and you are in latest firmware.
