VoLTE to VoNR handover

Hello Experts.

From Samsung 4G to 5G Ericsson and Nokia, we are making VoLTE to VoNR handover.

However UE is not sending b2 event in MR to eNB.

Did anyone face this issue?

I know it was succefully1 tested by Samsung team - only not sure whether it was VoLTE to VoNR or just data call…

Data is successful.

During VoLTE B2 was configured to UE?

No, it was not.

Then how UE will send MR?

Anyways, checking this.

That I know, thanks.

My question was more: did anyone face the issue and have tuned some Samsung parameters.
