The system comprises an off-premises voice or fax mail system and an on-premises CPE device that can periodically interrogate the telephone line to monitor for signals indicating that a voice or fax message has been received at the off-premises message system. The on-premises CPE device contains, or is connectable to, an incoming message storage means, an automatic dialing means, a message counter means, and a means for establishing an off-hook/on-hook condition with the telephone line. When a call comes in while the telephone line is busy, the call is directed to an off-premises message center where a message is stored. Then, the central office of the telephone network generates a special signal such as a stutter dial tone to be transmitted to the called party location upon the next off-hook condition after the previous call has been completed. Upon detection of a special signal generated on the telephone line that indicates a message has been received, the CPE device automatically establishes communication with the message system, and retrieves the message for storage and later review by the called party at the CPE device. If the called party happens to go off-hook during this automatic operation, the called party can monitor the message received while recording the message or can listen to the message and stop recording/transfer of the message while the CPE device is returned to a standby condition. Alternatively, a called party hookswitch at the CPE can be disabled until the message recording/transfer is complete.
