A method for registering a session initiation protocol (SIP) client to an internet protocol multimedia subsystem (IMS), in which a SIP client having a given IP address, public identity and private identity sends a registration request to a session border controller (SBC) for registering the public identity to the IMS, the SBC responsively causes an authorization request to be sent to another network entity in the IMS, the authorization request indicating the IP address of the SIP client and a private identity, the another network entity obtaining from an LDAP/AAA server a reference address based on the private identity and deciding whether to allow the authorization of the public identity to the IMS based on the correspondence between the reference address and the IP address of the SIP client.
