Maybe you could inform your client (MNO, MVNO, …) to open a ticket to Samsung.

It seams very weird UE answering with SIP 500.

Have you figured out what was the issue @RFSpecialist ? Is it related to Device OEM

Do you know what message this 500 is the answer for, from what you’re saying seems it should be the response of the INVITE and you are UEb. Can you confirm please?
