PURPOSE:To change a transfer destination from a remote location by preparing a specific pushphone code in addition to a telephone number, and using the code for registration control of a transfer destination telephone number of an incoming call transfer device. CONSTITUTION:When a caller 1 dials its telephone number A to a called party 6, an incoming exchange 3 of the called party 6 transmits a call signal to an adaptor 4. A pseudo response circuit 40 of the adaptor 4 responds thereto and informs a talkie to the caller 1. The caller 1 dials a pushphone code A' set to the adaptor 4 via a conventional incoming transfer device 5. The code A' is collated with the coincidence with the preset pushphone code by a collating circuit 45, a reception memory 43 and a semi-fixed memory 44 and when they are coincident, a message of a transfer destination telephone number reception is informed to the caller 1. The caller 1 transmits a telephone number A'' being the transfer destination set newly in a form of a pushphone signal. The signal A'' is received by the adaptor 4 and registered in the incoming transfer device 5 as a new transfer destination telephone number. |
