  • Patent number: 9100414
    Abstract: 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.
