Abstract
The number of simultaneous connections to a SIP server is increased without degrading overall performance. If it is judged that, when a newly requested call is accepted, the number of calls whose call control data is stored in a call processing memory or the amount of the call control data stored in the call processing memory would exceed an upper limit, the call control data stored in the call processing memory for a busy call is saved in an external storage device. As the frequency of occurrence of an event is low in the case of a busy call, it becomes possible to accept the new call without degrading overall performance.
