Abstract:
1. A method for reducing an impact of a source of unwanted voice messages in a call management system, the method comprising the use of one or more processors to perform at least a portion of one or more of the following operations: receiving a call request at a call server; determining a source of said call request; determining a time interval between the received call request and a previous call request from the source, information about said previous call request being retrieved from a database by a call manager; calculating a first parameter corresponding to a first time interval using the detected time interval; calculating a second parameter corresponding to a second time interval using the detected time interval, wherein the first and second time intervals overlap and wherein said second time interval is greater than said first time interval, at least part of the calculating being performed by at least one processor associated with the call manager; and using said first and second parameters to determine automatically if the received call is from a source of unwanted messages; and blocking connection by the call server of the call if the received call is determined to be from a source of unwanted messages.
