PURPOSE:To respond only to an incoming call with terminal designation information by a dial-in number or sub address in an incoming call control system for terminal equipment connected to a network terminating device. CONSTITUTION:A registration part 3 which registers the terminal designation information and the presence/absence of incoming call response, and a control part 4 which performs at least incoming call response control are provided at the terminal equipment 2-1 to 2-n or terminal adaptor connected to the network terminating device 1, and the control part 4 responds to the incoming call when the incoming call without the terminal designation information is received when the terminal designation information is not registered, and responds to the incoming call only when the presence of the incoming call response is registered when the terminal designation information has been registered. Also, when the incoming call with the terminal designation information is received, the control part responds to the incoming call in the case of no terminal designation information is registered and only in the case of the presence of the incoming call response is registered, and responds when received terminal designation information coincides by collating with registered terminal designation information when the terminal designation information has been registered. |
