Abstract

Terminal equipment on a reception side comprises a telephone number detection section for detecting a calling subscriber's number transmitted from the communication network, a memory for storing specified calling subscribers' numbers, and control section for calling back to the terminal equipment on the transmission side in case that it is detected in the memory by the telephone number detection section. Consequently, the terminal equipment on the transmission side promptly proceeds to a call or communication with the terminal equipment on the reception side only by dialing the telephone number of the terminal equipment on the reception side without dialing a call to the communication network, so that the terminal equipment on the transmission side can put the communication expense to an account of the terminal equipment on the reception side. It is also possible that the communication expense is put to an account of the terminal equipment on the reception side only for specified calling subscribers.
