E-CSCF Support

An Emergency Call Session Control Function (E-CSCF) is an IMS core element that aids in routing emergency calls to an appropriate destination, such as a PSAP. E-CSCF functionality can be performed by the Oracle Communications Unified Session Manager with appropriate local policy and network management control configuration.

The E-CSCF feature let the Oracle Communications Unified Session Manager internally prioritize and route emergency calls to the corresponding Emergency Service Center, based either on the calling party’s request URI, or based on location information retrieved from a CLF (Connectivity Location Function) for wireline/TISPAN networks.

By integrating E-CSCF functionality into the P-CSCF (Oracle Communications Unified Session Manager ), networks can satisfy the common local requirement that certain telephony elements be deployed locally, rather than use single, centralized elements. Funcitons like the E-CSCF likely fall into this category.
