Hi all,
When I dial to another telephone, how can I detect the signal to make sure that they are accept ?
I mean that how can detect the feedback signal when they press "OK" ?
Please help !
Thanks a lot.

I have never seen a phone with an "OK" button.
In my country we answer a phone call by going off-hook or turning-on the speakerphone. See, every country is different!
When the other end answers the call that I have dialed, the ring-back tone that I hear during their phone's ringing, stops. I don't remember but when they answer, maybe the phone company gives a momentary disconnection to my phone's DC, or momentarily reverses its polarity.
