I used to have Spectra and Jio WiFi calling on the iPhone used to be seamless. Switched to VoWifi as soon as it connected to the Wireless network. With Airtel, this is spotty. Sometimes it connects, sometimes it doesn't. Rebooting the phone or the router doesn't seem to help.
However, if I switch to Cloudfare DNS from Airtel's DNS on my router, VoWifi is perfect again. Has anyone else observed this? Is Airtel deliberately blocking Jio VoWifi?
