Hi Harshith Charging correlation among different operators is achieved through Inter Operator Identifier which is a globally unique identifier shared between operator networks. The originating IOI and terminating IOI are exchanged by the SIP request and response messages. The originating IOI is inserted by the originating CSCF in the P-Charging-Vector in SIP INVITE or other SIP requests. Similarly terminating CSCF inserts the terminating IOI in SIP responses in the P-Charging-Vector header
