SYSTEMS AND METHODS OF MANAGING COMMUNICATION REQUESTS IN A VOIP COMMUNICATION SYSTEM

摘要

An Internet protocol (IP) telephony system includes elements that prevent more than a specified number of simultaneous calls to be carried by the IP telephony system under a single user account. Multiple copies of a call session database are maintained in different geographical areas, and the multiple copies of the call session database are frequently and rapidly synchronized. The call session database is consulted before a new call is setup to determine if the user account that is to be used for the new call already is being used for a maximum number of simultaneous calls. If so, the new call setup request is denied.
