Abstract

The local telephone message announcing device automatically checks a remote telephone voice messaging system for stored messages in a consistent and timely manner, announces the presence of stored messages through an external indicator and automatically connects the user to the stored messages upon entry of a predetermined command by the user. The device checks for the stored messages by detecting a unique tone sent to a user'"'"'s telephone set or telephone number by the remote telephone voice messaging system to indicate the presence of stored messages. The detection occurs at predetermined time intervals whereby interference with the operation of the local telephone set is minimized. In addition, the device is easily installed by a person without technical expertise and can be adapted to any type of telephone set.

Claims

1. A local telephone message announcing device for signaling a telephone user as to the presence of one of more recorded messages that are stored by a remote telephone voice messaging system for a telephone number associated with a telephone line to which said message announcing device is connected, said message announcing device comprising:

detecting means for identifying one or more predetermined signals on said telephone line, at least one of said predetermined telephone line signals generated by said remote telephone voice messaging system and indicating the presence of a recorded message stored by said remote telephone voice messaging system, said detecting means including hook means for indicating an off hook signal for said local telephone, tone means for indicating a message waiting signal from said remote telephone voice messaging system, and ring means for indicating a ring signal for said local telephone;

control means operably coupled to said detecting means and to said telephone line for automatically initiating the detection of said predetermined telephone line signals generated by said remote telephone voice messaging system in response to a first preselected time interval after said ring means has indicated a ring signal, and also initiates the detection of said predetermined signal after a second preselected time interval after said first preselected time interval; and

notification means operably coupled to said control means for alerting said telephone user as to the presence of said recorded messages that are stored by said remote telephone voice messaging system in response to the identification of said predetermined telephone line signal.

2. The device of claim 1 wherein said control means further includes means for setting a continous monitor mode and automatically initiating the detection of said predetermined signal after a third preselected time interval if said continuous monitor mode is set.

3. The device of claim 1 wherein said control means initiates the detection of said predetermined telephone line signal by determining that there is no off hook signal, generating an off hook signal on said telephone line and monitoring said detecting means to determine the presence of said predetermined telephone line signal.
