CONSTITUTION:When guest room telephone set 1 dials a specific number to acquire idle preserving register 2 and dials a preserved time and an originating guest room number, they are set to storage circuit 7 through resister 2, and next, they are recorded on recording device 10 through control unit 8. At a determined time, time circuit 9 starts control unit 8 to take out all preserved contents and calls a pertinent guest room number and sends it trunk 3, and the guest room telephone set and trunk 3 are connected by the marker; however, in case of link busy, call is performed again by a recalling trunk after a fixed time. In case that link is busy at this time, timer circuit 9 records non-connection information on recording device 10 and indicates non-connection on audible indication unit 11.
