Method and device for providing direct inward dialling function in telecommunication exchanges

The method involves automatically accepting an incoming telecommunications connection. The caller is given an audible guide to the through-dial or re-dial function which requires him to enter re-dialling commands in the form of multiple frequency coded signals or speech commands contg. an identifier definitely associated with an extension (6,7,8) to be selected. The re-dial command is transferred to the telecommunications system like a speech signal and is converted into an electronic relay signal contg. an electronic extension identifier. Alternatively, the re-dial command is converted into an electronic relay signal, whereby the speech signal is associated with as predefined speech pattern associated with an extension and a relay signal is generated which contains an electronic identifier for this known extension. Manual relay by entry of a keyboard command is simulated by the relay signal which allows the telecommunications system to pass the connection to the ex tension corresp. to the redial command. An Independent claim is also included for an arrangement for implementing the method.
