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.
