SBC retains the same "icid-value" (which was is generated during the first egressed INVITE) during the Crankback/Redirected (3xx) call in the P-Charging-Vector header in an egressed INVITE. When the flag , storeICID, is enabled, all the CDRs (ATTEMPT/START/STOP) contains the same ICID value for Crankback/Redirected call in protocol specific string as well as in the original call records.

This is achieved by:

• Disabling pChargingVectorHeader transparency flag at the IP Signaling Profile attached with the TG, towards the IMS Core side.
• Enabling createPChargingVector flag at the IP Signaling Profile attached with the TG, towards the IMS Core side.
• Disabling storePChargingVector flag at the IP Signaling Profile attached with the TG, towards the UE.

acting as IBCF transparently passes the PCV received in any request from the P-CSCF to the IMS Core. Also, IBCF adds the stored PCV in the response to UE. This is achieved using the following configuration:

• Enabling pChargingVectorHeader transparency flag in the IP Signaling Profile attached with the TG, towards the IMS Core side.
• Disabling createPChargingVector flag in the IP Signaling Profile attached with the TG, towards the IMS Core side.
• Enabling the storePChargingVector flag in the IP Signaling Profile attached with the TG, both towards the UE side and IMS Core side.
