Abstract: In the presence information management method of the present invention, the e-mail address of the user and the terminal address of a terminal are extracted upon receipt of an e-mail transmission request, the e-mail address and terminal address correspondence table is retrieved by using the extracted e-mail address, and the extracted terminal address is registered in the e-mail address and terminal address correspondence table if the retrieved terminal address does not correspond to the extracted terminal address. Thus, the user can automatically update presence information with his/her e-mail transmission request.

Abstract: A load balancer includes a configuration information receiving unit that receives configuration information having address information of all the servers to which a request is directed and the type of service provided by each server, a load balance setting unit that configures so that a request transmitted from a client is transmitted to one of the servers corresponding to a service type specified in a message in accordance with the configuration information, and a band setting unit that calculates the number of the servers for each service type in accordance with the configuration information and assigns a band of a line to each service in accordance with the calculated number.

Abstract: A load distribution device that receives processing requests from terminals and that allocates and transfers the processing requests to at least one of a plurality of servers. The load distribution device includes a monitoring unit, a request receiving unit, an update server determining unit, a distribution ratio setting unit, a load distribution unit, a notification unit and an update completion detecting unit, whereupon receipt of a notification that the update of the server to be updated is completed, the update server determining unit determines that the update to the server to be updated is completed, determines a new server to be updated and a new server to be updated next, and instructs the distribution ratio setting unit to set the distribution ratios.

Abstract: To collectively manage user networks connected to a virtual private network (VPN) without such time and effort necessary for an operation management server to be ready for an expansion MIB for each of vendors.

Abstract: The present invention relates to an incoming call processing method for enabling immediate answering of the greatest possible number of incoming calls without generating unserviced phone calls, by determining whether to answer the incoming call immediately or to answer the incoming call at a later time at which the volume of incoming call traffic intensity is light. To this end, the method includes a call receiving step for causing an electronic exchanger to receive an incoming call, an incoming call acceptance step for determining whether to answer the incoming call received in the call receiving step immediately or to answer the incoming call at a later time at which the volume of incoming call traffic intensity is light, and an answer step for answering the incoming call according to the type of answer determined by the incoming call acceptance step.

Abstract: A channel reservation control system which reserves data channels in an appropriate manner to ensure the subsequent call set-up operations in automatic call distribution services. A channel allocation unit determines how many data channels should be reserved for a specific group of subscribers who may wish to use such reserved bandwidth. Then, a reservation request transmission unit makes a provisional reservation for as many data channels as determined by the channel allocation unit, and transmits a reservation request message to initiate the reservation of those data channels. Upon receipt of this reservation request message, a recipient-side reservation unit establishes channel reservation on the side of call recipients by securing the requested data channels for exclusive use by the specific group of subscribers.

Abstract: A system for controlling automatic call distribution service in a network in which call processing systems are connected via a control channel and a communication channel includes a pseudo-ACD-call-placement requesting unit which sends a request for pseudo-ACD-call placement from a control station to satellite stations via the control channel, wherein the control station is one of the call processing systems that receives a call from an exterior of the network, and satellite stations are the call processing systems other than the control station, a pseudo-ACD-call-placement-request accepting unit which accepts the request at the satellite stations so that a pseudo-ACD call is placed in queue in the satellite stations, and an inter-station-communication-path establishing unit which establishes a communication path via the communication channel between the control station and one of the satellite stations when the one of the satellite stations has an available receiver to respond to the pseudo-ACD call placed i

Abstract: There is disclosed an incoming call transfer controller for performing control so as to transfer a call incoming to a certain telephone terminal to another terminal.

Abstract: A method of controlling silent monitoring of a group in an electronic exchange accommodating a terminal of a monitoring individual and terminals of individuals to be monitored, wherein a call between a prescribed individual to be monitored and a customer is allowed to be monitored by the monitoring individual. The individuals to be monitored are divided into groups, groups to be monitored are allocated to the monitoring individual and this information is entered into a call controller of the electronic exchange. The call controller observes, group by group, call-in-progress/call-not-in-progress status of the individuals to be monitored and allows the monitoring individual to automatically monitor, in succession, calls between customers and call-in-progress individuals to be monitored belonging to the monitoring target groups allocated to the monitoring individual.
