Abstract

A system for remotely controlling call forwarding for a given telephone line, comprises detecting the receipt of a remotely transmitted identification code to the given telephone line, storing a desired call forwarding telephone number remotely transmitted after the identification code, and seizing the given telephone line and applying a call forwarding initiate code thereto followed by the stored telephone number. The receipt of a remotely initiated signal is detected at the given telephone line and the given line is seized upon a favorable detection and a call forwarding terminate code is applied.

10. The device according to claim 9, wherein the means responsive to the receipt of at least two calls comprises a counter receptive of ring signals and timing means for disenabling the counting of the counter after said preselected time interval.

11. A device for remotely terminating call forwarding for a given telephone line, the device comprising:

input means connectable to the given telephone line for receiving input signals remotely applied to the line;

output means connectable to the given telephone line for applying output signals thereto; and

means responsive to the receipt of signals for applying a call forwarding terminate code to the output means and comprising means for storing a received call forwarding time interval code corresponding to a desired time interval and timing means for producing the call forwarding terminate code upon the expiration of the desired time interval.

12. In combination:

a device for remotely controlling call forwarding for a given telephone line, comprising input means connectable to the given telephone line for receiving input signals remotely applied to the line, output means connectable to the given telephone line for applying output signals thereto, means responsive to the receipt of a preselected identification code by the input means for storing a desired call forwarding telephone number received by the input means with said identification code and for sequentially applying a call forwarding initiate code and thereafter said stored number to the output means, means responsive to the receipt of signals by the input means following said identification code for applying a call forwarding terminate code to the output means, a telephone answering machine, a switching means for connecting the signals from the telephone line to the telephone answering machine prior to the production of the first call forwarding initiate code and after the production of a call forwarding terminate code.

13. The combination according to claim 12, wherein the means for applying the call forwarding terminate code includes means responsive to the receipt of two calls within a preselected time interval for producing the call forwarding terminate code.

14. The combination according to claim 13, further means responsive to the absence of the receipt of said identification code within a preselected time period following the production of the call forwarding terminate code for sequentially applying the call forwarding initiate code and thereafter the last stored telephone number to the output means.
