Interim VoIP Architecture (i2)
Date added: Mar 5 - 08:37 pm
Document description:
Voice over Internet Protocol (VoIP) is poised to become the predominant technology used in the telecommunications industry. As the public adopts VoIP, E9-1-1 calls will increasingly originate from VoIP users. Some VoIP telecommunications service provider networks, however, are not natively compatible with the existing E9-1-1 infrastructure. This document was developed to outline an interim architecture to connect callers in the IP domain with Public Safety Answering Points (PSAPs) supported by the existing E9-1-1 Service Provider network.
This document is the NENA recommended standard for the i2 architecture to support the interconnection of VoIP domains with the existing Emergency Services Network infrastructure in support of the migration toward end-to-end emergency calling over the VoIP networks between callers and PSAPs.
This document provides an overview of the VoIP architecture, functional elements, and interfaces, as well as the interface specifications necessary for interconnection with the existing Emergency Services Network infrastructure.

Voice over Internet Protocol (VoIP) is poised to become the predominant technology used in the telecommunications industry. As the public adopts VoIP, E9-1-1 calls will increasingly originate from VoIP users. Some VoIP telecommunications service provider networks, however, are not natively compatible with the existing E9-1-1 infrastructure. NENA is developing a view of migratory (i2) and long-term (i3) solutions that will continue to support location-based routing of E9-1-1 calls and delivery of location-related information to PSAPs.
The migratory i2 solution (refer to NENA-08-001) makes use of a Validation Database (VDB) to ensure that civic location information representing VoIP end user locations is Master Street Address Guide (MSAG) valid, and includes an Emergency Service Zone Routing Database (ERDB) function used for real-time routing of E9-1-1 calls. The i3 solution is expected to have similar needs.
