Endpoints may be SIP phones or legacy phones (Analogue or ISDN) connected to a gateway. All services by HES are provided by applicati

46、on servers using standard IMS procedures. User may access services that are specific to the enterprise they belong to as well as services available to any other IMS users. In more complex configurations some of the endpoints may be connected to a 3GPP IPCAN and/or a circuit-switched network, which i

Endpoints served by a HES shall have the ability to setup a session, identifying the communication target by: - a SIP URI of the form user domain; - an E.164 telephone numbe

48、r; - a number within a private numbering plan; - local service numbers. With regard to supplementary services, HES have strong similarities with the provision of PSTN/ISDN simulation services, although the actual set of services may be different. Examples of services that are enabled by the architec
