Not able to make voice calls in 4G Volte, in rooted Moto G3

Have rooted the Moto G 2015 edition, installed “STOCK Motorola 6.0.1 ROM- OPTIMIZED” custom rom with Xposed module. Now I am not able to make voice calls in 4G. When i put a Jio sim (4G LTE sim with VOLTE), I'm not able to activate voice calls and sms. But Volte support is shown in the notification bar. Have enabled LTE in the settings also using the secret code. But while dialing 1977 for activating voice calls, the call won't connects and it hangs. And after 30 seconds, the network coverage will goes off and the call will stop without even connecting. Anyway to enable Volte support in this rooted device? Volte is working fine in Moto G3 with stock android.
Even though its stock but its not completely stock, that's why it doesn't support VoLte. Currently only VoLte working rom is pure stock and it also work even if you rooted.

No way to re-enable volte support in rooted phones???
As I said above VoLTE supports on stock rooted but not the one you flashed " stock optimized " version.

No, as for now none of the custom rom supported. Maybe in coming days Exodus rom will add this feature as stated by maintainer.

If you have Installed it correctly and you're running the latest OxygenOS but it doesn't work,make sure your Network carrier supports it ....you can contact and ask them
(yes,many users have the same problem in different countries)

Yea i have a carrier which supports vowifi(JIO 4G) as well as the latest updates installed but i still cant manage to get vowifi working. I tried changing the dns of my router and several other teoubleshooting but none of them seems to work. Some people say port forwarding might make it work but i havent tried it yet.
My carrier supports volte and vowifi but not for our device (OnePlus 7) but with this guide i have both volte and vowifi working
Give it a try

But when i connect to a wif hotspot of another phone, the vowifi icon appears on the status bar. The problem might be with the wifi settings of the router or the ISP not necessarily the phone.

Good news is the latest WW firmware for me actually enabled VoLTE as a menu option by default, even when it wasnt listed in the patch notes. Now, I dont know if they added any carriers but I know there was a list of MBN's on ZenTalk of ones that were already inserted into the modem firmware, so if your carrier is on that list theres a very good chance that VoLTE will work.
Tried the update still its not supported.

Not supported how? Which carrier do you have?
its called Zain in Kuwait. Tried samsung phones and they are working fine but not on the ASUS rog 5. Note: the 5g is working fine. However when dial *#*#4636#*#* and checking the IMS it says not registered and VoLTE and the rest unavailable.
