Call screening device
View Patent ↗Devices and methods are disclosed herein which allow a telephone call screening device to be connected in parallel to the remaining extensions within a home.
1. A call screening device for telephone systems having at least two parallel wired telephonic outlets, the screening device comprising; a telephone line input wired to a first telephonic outlet wired in parallel with at least one other telephonic outlet and call handling electronics and a screening criteria stored within the electronics, wherein upon receiving an incoming call via the line input, the call screening device picks up the line to answer the call, executes the screening criteria upon the call; if the criteria returns a “pass”, the electronics issue a hook flash command upon the telephone line and then hangs up the line, thereby causing the line and devices connected to parallel outlets to ring again.
2. The call screening device of claim 1 , wherein the screening criteria is a reverse Turing test.
3. The call screening device of claim 2 , wherein the screening criteria selects a random number that is read to the caller which the caller must then correctly enter as DTMF tones.
4. The call screening device of claim 2 , wherein the screening criteria is a question which is irrelevant but effortless to answer for a human caller, including for instance, “what year is it?”, “what vegetables are in a tomato soup?”, “how many arms does a person have?” or other reverse Turing test known in the computational arts.
5. The screening device of claim 1 , wherein after a “fail” result, the caller is played a recorded message before the device hangs up the line.
6. The screening device of claim 1 , wherein after a “fail” result, the caller is given the option of recording a message for the called party before the device hangs up the line.
7. The screening device of claim 1 , wherein after a “fail” result, the electronics hangs up the line, thereby disconnecting the call.
8. The screening device of claim 1 , wherein the screening criteria is a blocklist.
9. A call screening method for telephone systems implemented on an electronic device, with the method comprising; providing first telephone line input wired in parallel with at least one other telephone line, providing call handling electronics wired to the telephone line, and providing a screening criteria stored within the electronics, wherein upon receiving an incoming call via the telephone line, the call screening electronics picks up the line to answer the call, executes the screening criteria upon the call; if the criteria returns a “pass”, the electronics issue a hook flash command to the telephone line and then hangs up the line, thereby causing the line and all parallel lines connected to it to ring again.
10. The call screening method of claim 9 , wherein the screening criteria is a reverse Turing test.
11. The call screening method of claim 9 , wherein the screening criteria selects a random number that is read to the caller which the caller must then correctly enter as DTMF tones.
12. The call screening method of claim 9 , wherein the screening criteria is a question which is irrelevant but effortless to answer for a human caller, including for instance, “what year is it?”, “what vegetables are in a tomato soup?”, “how many arms does a person have?” or other reverse Turing test known in the computational arts.
13. The screening method of claim 9 , wherein after a “fail” result, the caller is played a recorded message before the device hangs up the line.
14. The screening method of claim 9 , wherein after a “fail” result, the caller is given the option of recording a message for the called party before the device hangs up the line.
15. The screening method of claim 9 , wherein after a “fail” result, the electronics hangs up the line, thereby disconnecting the call.
16. The screening method of claim 9 , wherein the screening criteria is a blocklist.
