This Technical Report is one of a series of publications that provides an overview of IP-based enterprise communication involving Corporate telecommunication Networks (CNs) (also known as enterprise networks) and in particular Next Generation Corporate Networks (NGCN). The series particularly focuses on session level communication based on the Session Initiation Protocol (SIP) [6], with an emphasis on inter-domain communication. This includes communication between parts of the same enterprise (on dedicated infrastructures and/or hosted), between enterprises and between enterprises and public networks. Particular consideration is given to Next Generation Networks (NGN) as public networks and as providers of hosted enterprise capabilities. Key technical issues are investigated, current standardisation work and gaps in this area are identified, and a number of requirements are stated. Among other uses, this series of publications can act as a reference for other standardisation bodies working in this field. This particular Technical Report discusses issues related to emergency calls from an enterprise user to a public or enterprise emergency response centre (ERC) using SIP within the NGCN. It uses terminology and concepts developed in ISO/IEC TR 12860 [1]. It identifies a number of requirements impacting NGN standardisation and concerning deployment of enterprise networks. The scope of this Technical Report is limited to calls from an enterprise user to an authority, where the authority is represented by a public or a private ERC. This includes the special case where a private ERC acts as an enterprise user in making an emergency call to a public ERC. Authority to authority calls, authority to enterprise user calls and enterprise user to enterprise user calls within the context of an emergency are out of scope. This Technical Report focuses on emergency calls within a SIP-based NGCN using geographic location information to indicate the whereabouts of the caller. Emergency calls can originate from devices connected to the NGCN via various access technologies, e.g., SIP over fixed or wireless LAN (Local Area Network), TDM (Time Division Multiplex) networks, DECT (Digital Enhanced Cordless Telephone) networks, PMR (Private Mobile Radio) networks, PLMN (Public Land Mobile Network) etc.. ERCs are assumed to be reachable either directly using SIP or via a gateway to some legacy technology (e.g., TDM). Furthermore, ERCs are assumed to be reachable either directly from the NGCN or via a public network accessed from the NGCN using SIP. In the latter case, the NGCN might identify the ERC and instruct the public network to route to the ERC, or alternatively the NGCN might leave the public network to identify the ERC, based on the location of the caller. In all cases the NGCN is assumed to deliver the location of the caller to the ERC, gateway or public network in order to provide appropriate information to the call taker at the ERC. The handling of incoming emergency calls at an ERC, even when the ERC is provided within an NGCN, is outside the scope of this Technical Report. This includes the case where a public ERC is provided within an NGCN and hence the NGCN can receive emergency calls from public networks. This also includes the case where a private ERC is provided within an NGCN and can receive emergency calls from other enterprise networks. Different territories have different regulations impacting emergency calls, together with national or regional standards in support of these regulations. This Technical Report takes a general approach, which should be largely applicable to any territory. However, detailed differences might apply in some territories, e.g., countryor region-specific dial strings such as 911 and 112 used to identify emergency calls to a public ERC. The scope of this Technical Report is limited to emergency communications with a real-time element, including but not limited to voice, video, real-time text and instant me
