Welcome to Android Central! Have you already tried talking to Jio about it?

From what I can find on the web, it looks like Jio might rely completely on 4G for voice calls (i.e., VoLTE or Voice over LTE). If your phone doesn't support VoLTE on Jio's network, then you won't be able to make or receive calls.

Jio doesn't use 2G - but it doesn't use 3G either, so the phone has to be 4G unless the OP is using WiFi for data.

Yeah, I figured that they're connecting to 4G for data, but either VoLTE isn't turned on or the phone doesn't support VoLTE on Jio.
