Abstract (en)
[origin: DE10150492A1] A dial-repeat process is carried out automatically at preset time gaps within a preset time window. A responsible telephone exchange initiates an automatic dial-repeat process. A caller's telephone handset/mobile telephone also initiates an automatic dial-repeat process. The call number of the number called and the call number of the caller are stored at the exchange/relay point for a preset period of time. An Independent claim is also included for a device for carrying out a dial-repeat process in telecommunications networks for callback when not in use.
