ABSTRACT:
A conference adapter. In an illustrative embodiment, the conference adapter implements a method for interfacing one or more conference endpoints with one or more conference servers. The method includes registering an endpoint and a conference server to determine endpoint registration information associated with the endpoint and to determine conference-server registration information associated with the conference server. Next, the method includes receiving a connection from the endpoint and a connection from the conference server. Subsequently, the conference adapter establishes communications between the endpoint and the conference server as initiated by the endpoint and based on the endpoint registration information and the conference-server registration information. In a more specific embodiment, the method further includes receiving plural connections from conference servers of disparate types, and then selectively switching communications between the endpoint and a first conference server to communications between the endpoint and a second conference server. The method further includes selectively switching endpoints for a given conference session.
