Welcome to the Emergency Services Interconnection Forum (ESIF)
ESIF provides a venue to facilitate the identification and resolution of technical and/or operational issues related to the interconnection of emergency services networks with other networks (e.g., wireline, cable, satellite, Internet, etc.).
ESIF is an open technical/operational forum to identify and resolve interconnection issues through the voluntary participation of interested parties. The interest of all members will be served by observing the principles of openness, fairness, consensus, and due process.
ESIF develops standards and other documentation for the interconnection of emergency services networks. ESIF will liaise with industry, governmental, standards, and public safety organizations to apprise them of its deliberations and decision, and ensure the proper coordination of activities. Discussion will be focused on the application of current and emerging technologies to maintain and support the interconnection of emergency services networks.
ESIF works closely with the National Emergency Number Association (NENA), which serves the public safety community by focusing on 9-1-1 policy, technology, operations, and education issues. A summary of the ESIF-NENA relationship can be found at ESIF-NENA Relationship and two diagrams depicting the relationship can be found at ESIF-NENA Relationship Diagrams.
The ESIF Next Generation Emergency Services (NGES) subcommittee is currently working on a new ATIS standard to define the call processing, transport, and delivery of Emergency Service calls within the NG9-1-1 network. This work (ESIF Issue 74) will build upon the NENA i3 requirements (NENA 08-751 Issue 1) to outline requirements for applying 3GPP Common IMS to the NG9-1-1 environment.
The ESIF Next Generation Emergency Services (NGES) Subcommittee is the lead for the IMS911 joint work effort, which addresses the next phase of defining the processing, transport, and/or delivery of Emergency Service calls within the NG9-1-1 network to the appropriate PSAP (ESIF Issue 81). This initiative is a joint effort with the Packet Technologies and System Committee (PTSC) and the Wireless Technologies and Systems Commitee Systems and Network Subcommittee (WTSC SN). Issue 81 is a continuation of work previously completed by the ESIF NGES for defining the call processing, transport, and delivery of Emergency Service calls within the NG9-1-1 network (ESIF Issue 74).

The ESIF NGES is also providing essential industry input to two ATIS Wireless Technologies and Systems Committee (WTSC) projects:
- The Implementation of 3GPP Common IMS Emergency Procedures for IMS Origination and ESInet/Legacy Selective Router Termination (WTSC Issue P0030)
- Automating Location Acquisition for Emergency Services VoIP Calls (WTSC Issue P0034)
The Wireless E9-1-1 Phase II Readiness Package is one of ESIF's primary work products. Developed to supply PSAPs with a standard method for verifying readiness and providing carriers with complete information to speed implementation, the PSAP Readiness Checklist is part of a three-part package that also includes an introductory letter and instructions document and an Appendix.
