<P>PROBLEM TO BE SOLVED: To provide a call control server which is capable of efficiently executing call control and easily changing control information, and a call control method. <P>SOLUTION: A call processing control apparatus includes a user agent function unit 64 and a sequence function unit 65. When a signal about call control is received from any server and if a signal to be responded back to a transmission source can be uniquely identified from a class of the received signal, the user agent function unit 64 transmits this signal to be responded for a response back to the server of the transmission source of the signal about call control, but if not uniquely identified, the user agent function unit 64 transmits the signal to be transmitted which is identified by notifying the sequence function unit 65 of this, to a server to which this signal should be transmitted, specified on the basis of this signal. In the case where it is notified that the signal to be responded is not uniquely identified from the class of the received signal in the user agent function unit 64, the sequence function unit 65 specifies the signal to be transmitted in accordance with a held sequence pattern being executed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
