A telephone exchange, for example a PABX installation, is equipped with stations/extensions (A', A') and is so arranged that predetermined stations/extensions are able from their own instrument to initiate referral/transfer of calls, i.e, automatic referral or automatic transfer, using dialling devices or some similar arrangement on or adjacent to the instrument. Paging equipment and/or a bank of telephone answering machines are connected to the exchange so as to be accessible in the same way as ordinary stations or extensions. Each paging device and/or telephone answering machine is so arranged as to serve as a receiving device for the automatically referred or automatically transferred station/extension. Any incoming call to the automatically referred or automatically transferred station/extension will be diverted to the appropriate receiving device, via or by means of which the caller can be connected to the station /extension or informed of the fact that he is being referred/transferred, or even provided with additional information, e.g. the reason for the referral/transfer or the time of return, etc. In this way the caller need not be familiar with the paging and transfer procedures, etc., within that particular exchange which are necessary in order to be connected to or to obtain information about the station/extension concerned. |
