I express my sincere thanks to all forum members for there great support
without whom this project wouldn't have been a reality.

Still I am welcoming new ideas to improve my final circuit.

7805 labels are reversed, I will clear it.
at board 3 there should be 4.7K replaced with 470 Ohm and a 1K preceding all LED s.

Hi there,


Oh yes, this certainly does look like a very interesting project indeed. I wouldnt mind taking a better look at it myself but unfortunately that site you posted the link on does not show up in my browser very well for some reason and i've tried over and over again and it doesnt work. If you could post a pdf schematic that would be great.

Where & How DTMF details in my contact details used? In my N73, i see that I can add "DTMF" details to each contact. I would like to know where and how this DTMF info is used? I understand DTMF is used for identifing which key was pressed, please tell me some use cases.
