CSCF: Call Session Control Function
Call Session Control Function (CSCF) is a functional entity within IP Based Multimedia Subsystem (IMS) and part of 3GPP UMTS Reference Architecture. CSCF performs signalling operations for call session control. It manages SIP sessions and coordinates with other network entities for session control, service control and resource allocation. To fulfil such functionalities, the CSCF can act as Proxy CSCF (P-CSCF), Serving CSCF (S-CSCF) or Interrogating CSCF (I-CSCF).
