I cannot believe the attitude you have Talhaz Hakim. You are so demanding and come hell or high water you seem to think that just becasue you want something that it is going to materialize. Any REAL engineer would try to take the ideas that have come forth so far and then try to design and build something. If it didn't work they would then tinker with it until they got it to work. If they couldn't get it to work they would then take the time to carefully document what they have done so far and post it along with a specfic question like..."Why does this Q1 transistor not saturate?"....or...."How can I get the T2 pin of the 89C52 to drive the off-hook relay properly?"

With the attitude that you have presented there are probably few here who are willing to give much help. I know for one that I will not respond to your demanding approach. And I am certainly not going to design any circuits for you.
