A synch server comprises a first interface configured to transmit and receive MAP messages, and communicate with a Home Location Register (HLR) in a Circuit-Switched (CS) network, a second interface configured to communicate with a Home Subscriber Server (HSS) in an IP-Multimedia Subsystem (IMS) network, and a third interface configured to transmit and receive Extensible Markup Language (XML) Configuration Access Protocol (XCAP) messages. A synch function module is configured to receive a message containing a change to a supplementary service setting associated with a User Equipment (UE) connected to a Circuit-Switched (CS) network or an IMS network, and communicate the change to the supplementary service setting to both the HLR and the HSS so that the supplementary service settings in both the HLR and the HSS are updated to reflect the change to the supplementary service setting.
