Romeu Medeiros medeiros at medeiros.eng.brHello Sukchan and friends. I'm trying to use the CSFB in test lab, and every time that nextepc send the UEContextModificationRequest, the UE respond with an UEContextModificationFaliure [ Protocol-cause=semantic-error ]. [image: image.png] I'm looking why I'm getting this. Someone have any idea?
