### Description Hello,

I have just upgraded our IMS core to the very last version. However, when I try to register one user (Alice) the SIP REGISTER does not reach the SCSCF. After having captured packets flow I realized that it was fault of I-CSCF. I saw DWR/DWA messages between HSS and ICSCF so I assume that the Diameter connection is successfully estalbished. However, no UAR message is sent from I-CSCF to HSS.
