A telephone central office system incorporating a toll service desk with special switching equipment including toll recording trunks which reduces the extent of operator participation in processing telephone calls, and which uses a reduced number of trunks to effect improved service. Operators at the toll service desks can handle call items in any order, but cannot release a call until all requirements are met. In calls requiring operator participation, the operator may release once the service necessary to establish or forward the call is given, and is relieved from manually having to make out tickets on any calls except on calls to subscribers in non-dialable offices involving alpha-numeric directory numbers. Special features of the system include flash recall of an operator at any time on any call, automatic answer time display upon flash recall from a non-coin station, automatic answer time display during the initial period and elapsed time display after the initial period upon flash recall from a coin station, reestablishment without rekeying of a call in the forward direction after flash recall, automatic or manual insertion of time and charge and class-change, and changing a call status by the operator from station-to-station to person-to-person and vice versa.
