ABSTRACT:
A telephone operator simulator system comprises a desk top device connected to a telephone line and which is enabled for operation by the detection of a ringing signal on the line. The system includes a keypad which is selectively operated by the user to cause the system to "answer" the phone by supplying a pre-recorded synthesized voice message over the line. This message is followed by the production of a suitable synthesized background sound during the time the calling party states his or her request. The user then operates another key on the keypad, and the same synthesized voice provides a second message, and places the calling party on hold. The user then uses any conventional phone connected to the same line to communicate with the calling party. When this second phone is placed "off-hook", the operator simulator system is turned off or disabled, and a normal telephone conversation takes place between the user and the calling party.
