Abstract
A system for increasing call capacity of an internet telephony system in an emergency mode, such as where there is a surge of call requests in a particular region. A management system in the internet telephony system may detect the presence of an actual or potential state of congestion of call traffic and/or signaling traffic. In order to admit a higher rate of call traffic to the telephony system, action is taken to reduce the workload of the signaling system, in order to allow the telephony system to focus more on serving call requests. For example, the signaling system may reduce the rate of signaling request messages processed with respect to requested and ongoing calls and/or reduce the amount of processing involved in handling such messages.
