Abstract
A method and system for collecting and communicating contextual information relating to a VoIP conversation is provided. Structured hierarchies are utilized for efficient communications of various amounts and types of contextual information relating to a VoIP conversation. Information identifying at least one structured hierarchy, which will be used to carry the contextual information, is transmitted during establishment of a conversation between two VoIP enhanced devices. The structured hierarchy is selected from a set of predefined and declared structured hierarchies. Subsequently transmitted contextual information exchanged between two VoIP enhanced devices is represented in accordance with the identified structural hierarchy. VoIP clients, network infrastructure, and various service providers can collect the contextual information based on the identified structured hierarchy, update the contextual information by adding, deleting and/or modifying the contextual data. The updated contextual information will be transmitted to other clients, network infrastructure, and service providers.
