Hi Expert,
Could someone please suggest what could be the reason on VoLTE setup failure while we have ongoing 5G downloading session?

in NSA, 4G is for signaling. After attached 4G/5G, UE context is managed by enodeB & MME.
I suggest you to collect S1 L3 message tracing to know when VolTE setup request, MME will ask enodeB to modify UE context, maybe enodeB reply with a failure, you can find the cause.
