Developer Program - OpenScape First Response ESInet/NGCS Solution

The components in the OpenScape First Response ESInet/NGCS Solution are implement to be compliant to both the North American (NENA) and European (ETSI/EENA) standards. Projects outside North America and Europe will tend to use the ETSI/EENA standards, so the solution can be deployed anywhere in the world.

All external interfaces provided by the solution will be compliant to the applicable standards. This page will enumerate these interfaces and describe which standards apply. Internal interfaces between solution components provide by Unify/Atos will not be described here.

Incoming Emergency Call SIP Interface

All emergency calls arriving at the BCF interface to the ESInet are signaled via the Session Initiation Protocol (SIP). In North America, per the NENA standards, calls on this interface are expected to provide links to additional data structures in Call-Info headers, but the solution can handle calls without these links. Per ETSI/EENA standards the inclusion of links to additional data are optional and are only of interest to the PSAP.

The SIP interface to the NGCS solution is compliant with RFC 3261 and to the relevant sections of the NENA i3 document and ETSI TS 103 479.

This interface is represented by the dotted red line B in the diagram above.

There have been no changes to this interface in recent versions of the NGCS solution.
