1. A method for controlling a voice-over-Internet (VOIP) network including session controllers for calls on the VOIP network, said method comprising: obtaining, by an administrative server, information on the VOIP network concerning one or more VOIP calls gathered at one or more session controllers which control setting up, maintaining and tearing down calls at different network locations; analyzing, by the administrative server, the information received from a first session controller to determine whether any of the VOIP calls between a gateway associated with said first session controller and an additional gateway associated with a different session controller are inactive; and sending, by the administrative server, at least one command to one or more of the session controllers that causes the one or more session controllers to drop any VOIP calls that are determined to be inactive based upon the analyzing of the information received from the first session controller.
