Are you using Airtel . And is this happens only for AIRTEL TO AIRTEL VoLte call.?

Yes - you get a busy tone with AIRTEL VOLTE calling up any phone - iphone and others too. Its bit confusing as first I too thought the other person is busy but later on got used to it. Anyways, I am not using VOLTE anymore as I feel there is a higher battery discharge using it - my experience.

This issue dates back to the time when AIRTEL launches VoLte in 2017. Atleast for you they fixed it. But for me it exists till now. Airtel never consider it as issue. I am used to it like how i used to be ready for ASUS buggy software 1.5 years back.
