I was using VOLTE services (from reliance jio in India) seamlessly since November 2016, but since June 2017 it suddenlt stopped working. I get an error "Unable to place call. Please try another method" while trying to make a call. I am able to access the internet and make/recieve calls from the Jio 4G Voice app.
UPDATES:
- I have enabled "enhanced 4G LTE mode"
- Did a factory reset
- My jio connection is on and working. Also, I can place/receive calls from the
Jio4GVioce
app which means the service is working fine.
