E-CSCF Emergency - Call Session Control Function
The E-CSCF is a specialist platform which is designed to facilitate support for emergency services dialling. In this capacity, the E-CSCF will take in requests from the P-CSCF (Proxy CSCF) and S-CSCF (Serving CSCF) and route these emergency session requests to a suitable onward destination such as a PSAP (Public Safety Answering Point). In order to achieve this, the E-CSCF can use the services of the LRF (Location Retrieval Function).
