The Voice over New Radio (VoNR) in 5G is similar to VoLTE in 4G.
In VonR, UE can have both voice & data services on 5G network.

- No, as per Rel-15, there is no support for voice call continuity between 5G and 3G Circuit Switched (CS)

- Yes, When the UE moves out of ππ coverage, inter-RAT handover is initiated, and VoLTE is provided in the LTE coverage area instead, but we must enable N26 interface between 5G-AMF & 4G-MME
ππ¨ππ: Without N26 interface Voice call handover is not possible between 5G to 4G due to Voice interruption time.
