摘要： The invention relates to a system for consuming at least one Web service (2) provided by a provider device wherein said provider device is identified by an address or URI which is the SIP URI address. According to the invention, said Web services provider is discovered and located by means of initiating SIP sessions. In this system: a user client (1) of the Web service generates a session initiation request indicating as the URI of the request the SIP URI of the provider and describing said session by means of SDP in which an interaction context is described to negotiate the consumption of said service, where said interaction context includes at least the URL from which the Web service can be invoked and a message exchange pattern MEP, said provider generates a session initiation response described by means of SDP including said interaction context proposed by the client or modifying it, such that if the Web services provider is registered in that SIP network, the client accesses the service using the SIP URI of the provider.
