Call server selection
View Patent ↗In a click-to-call communication environment, the present invention is employed to select an appropriate call server to use when establishing a call between two endpoints. A computing terminal provides a request to initiate a call between the two endpoints. The request is passed to a service node directly or through any number of intermediate nodes, such as a web server. The request may identify a source and a destination for the call. The service node will select a call server to use for establishing the call between the two endpoints based on the destination for the call, and send instructions to the call server to initiate the call. In response, the call server will initiate the call between the two endpoints.

wherein the call server selection comprises:
selecting a first call server;
obtaining a status of the first call server; and
determining whether to use the first call server as the selected call
server based on the status of the first call server; and send, to the selected call server, instructions to establish the click-to-call communication session between the telephony terminal of the user and the specific destination endpoint, the instructions providing the address of the telephony terminal associated with the user and the specific destination address of the specific destination endpoint.
