The working of telephone is very simple, When you get a call, a high voltage signal is sent to your phone which makes the phone ring. When you lift the handset, the switch under it is released, which disconnects the ringer and connects your mic to main line.
Expected Output:
- I will make a device whose size is as small as thumb which has a male and female telephone ports. You have to plug your telephone wire into the device and device is pluged into the phone like a bridge between phone and wire. It will know when you get a call, wait for 3 seconds, attends the call without lifting the handset, waits for 2 seconds, push the button, after two seconds cuts the call.
- To push the button I will either use a servo mechanism or a parallel switch mechanism based on the type of intercom you are using.
