A method and apparatus for enabling registration of an Aggregate End Point (AEP) device that is incapable of supporting a Session Initiation Protocol (SIP) based Internet Protocol Multimedia Subsystem (IMS) registration are disclosed. The method performs a static registration of the AEP device in a plurality of network elements associated with an Internet Protocol Multimedia Subsystem (IMS) network by provisioning. The method then processes an originating call request or a terminating call request associated with the AEP device using the static registration.

Method and apparatus for enabling registration of aggregate end point devices through provisioning

A method and apparatus for providing a reliable Voice Extensible Markup Language (VXML) over packet networks such as Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) network are disclosed. For example, a service provider may utilize a plurality of content servers that can be accessed by at least one telephony browser. The telephony browser can reach the content browsers directly as well as through a shared server that may load balance among the content servers. When a request for a VXML content, e.g., a VXML application, is received, the telephony browser sends the request to the shared server. If the request fails or a response is not received prior to expiration of a predetermined time interval, then the telephony browser sends a second request directly to one of the content servers that is capable of providing the requested content.

Method and apparatus for providing a reliable voice extensible markup language service

A method and an apparatus for providing multi-homing to an aggregate endpoint device over a network are disclosed. In one embodiment, the method receives a session request directed towards a user endpoint device by a routing device. The method receives at least one Public User Identity (PUID) for the user endpoint device if the session request is for a subscriber of a service with multi-homing via an aggregate endpoint device. The method selects a route for sending the session request in accordance with the at least one PUID and a route priority information of the PUID associated with the user end point device, wherein the route with a highest priority is selected, and forwards the session request via the selected route.
