Abstract: A telecommunications system uses software applications called user agents, that are preferably Internet-based and that operate on behalf of users in a telecommunications hosting server to control call connections under control of a telecommunications network server that interfaces with the telecommunications hosting server as well as a connection-based public telephone network. The telecommunications hosting server operates on a computer network on behalf of the user agents to provide call signaling in support of many advanced calling and telecommunications services. The functionality and performance (e.g., execution) of the user agent(s) preferably takes place primarily within the telecommunications hosting server, though user client computers can provide some and possibly all of the user agent functionality, depending upon the particular implementation chosen.

Abstract: Mechanisms and techniques provide a system for performing messaging between a message server and a message client. Embodiments operate to receive a first message to be sent to a messaging client and establish a first connection to the messaging client. The system then transmits a message processing script and the first message over the first connection to the messaging client. The message processing script enables the messaging client to display the first message and to receive and display at least one second message over the first connection to the messaging client. The system maintains the first connection in an open state after transmitting the first message to the messaging client. The system then receives a second message to be sent to the messaging client and transmits the second message over the first connection to the messaging client for receipt by the message processing script, while continuing to maintain the first connection in an open state.
