Patent ID: 8665312

Claim:
A transmission management system, comprising: a storage device to store refrained state information indicating a refrained state of a transmission terminal in association with operation state information indicating an operation state of the transmission terminal having the corresponding refrained state, the operation state being determined to be: (1) an error state when the transmission terminal has the refrained state that is caused by a trouble in function of the transmission terminal that is related to transmission or reception of sound data to or from a counterpart transmission terminal; and (2) a normal state when the transmission terminal has the refrained state that is caused by at least one of: a trouble in function of the transmission terminal that is related to transmission or reception of image data to or from the counterpart transmission terminal; and activation of restriction processing that restricts a communication function of the transmission terminal; a network interface to receive refrained state information indicating a refrained state of a first transmission terminal from the first transmission terminal; and a processor to obtain operation state information that is stored in association with the refrained state information received from the first transmission terminal, as operation state information of the first transmission terminal; and cause the network interface to transmit the operation state information of the first transmission terminal to a second transmission terminal that may initiate communication with the first transmission terminal.
