Reasons why 5G Core is not providing VoNR

Hi all 5G Experts.

For 5G SA, if 5G Core is connected to the IMS server, what may be the reason for not providing VoNR?

One reason might be 5G RAN doesn’t support 5qi = 1 permanently, right?

Any other suggested reasons?


I’m here talking about the Brazilian scene.

The greatest difficulty in implementing VoNR is not related to the network, but to smartphones. Today, we don’t have any homologated smartphone that works with VoNR.
