ABSTRACT:
A verification code from a telephone terminal which requests a call forwarding service is registered into a switching system. When a call forwarding service establishing number is dialed from an arbitrary telephone terminal, the arbitrary telephone terminal is prompted to dial the registered verification code and a telephone number thereof. The switching system checks the dialed verification code against the registered verification code. If they coincide with each other, the switching system prompts the arbitrary telephone terminal to dial a call forwarding service establishing special number, the telephone number of the telephone terminal registered in the service and a forwarding destination telephone number, and then establishes a call forwarding service setup for the telephone terminal registered in the service.
