TelephonyManager.java have a function to check isVolteAvailable(). You can call that function to know the status of voLTE.

The linked code for `isVolteAvailable()` is annotated with `@UnsupportedAppUsage` meaning it is not intended for use by end users. See https://stackoverflow.com/questions/52499754/what-does-unsupportedappusage-annotation-depict – asky Jul 18 '21 at 23:16

If you can connect to at port then by using standard at commands, this can be verified.

at+cops? => this will give information about the current latched cell. check if the mobile is currently on LTE(7) cell.
make volte call and shoot the at+cops? again. If the call is connected and mobile is still in LTE(7) cell, then its for sure VoLTE call.
