What 3GPP IMS IP Multimedia Subsystem Release 16 - SIP Signalling, P-CSCF Security and Emergency Call Procedures requires
This standard mandates that telecommunications operators implementing IP Multimedia Subsystem (IMS) Release 16 must establish secure signalling interfaces using IPsec or TLS between the User Equipment (UE) and the P-CSCF, and between network nodes, to ensure confidentiality and integrity for all SIP communications, as specified in 3GPP TS 33.203.
