Interrogating - Call Session Control Function(I-CSCF)

The I-CSCF serves as the routing and querying component in the IMS core network. It operates at the network boundary, handling incoming SIP requests, routing them to the appropriate S-CSCF, and interfacing with the HSS to retrieve user profile data. It is essential for roaming support and network topology concealment.
