A radiotelephone device (10) having an interface (12) for connecting to a telephone (11) for receiving signals (e.g. DTMF signals) generated from a keypad (14) of the telephone apparatus. The device has a decoder (26) for decoding signals received from the telephone, a display (28) arranged to display menu items and a controller (20) coupled to the display and the decoder for causing the display to display selected menu items including at least a message write-send and/or receive option in response to signals received from the telephone. Thus, a simple, cost-effective way is provided for connecting a telephone or PBX directly to a GSM or other radiotelephone network. |
