Hi, That was an amazing and factual explanation from VisBabu... great work da... Yesterday, I did the beta testing of my micorfone+headfone by calling up a voice-conversation b'n all my infy-friends. That was a great success... Just as u might expect, we didn't speak anything sensible... with 9 people from across Pune, Bhubaneshwar, Chennai and Mangalore its obvious nobody is going to make any sense amid the commotion. But the purpose was to test the scenario and it worked like beaut. And, for all u people who have microfones, if u come online, just remember to enable voice...coz, technology is improving... Ponder of the day... Have you ever thought what life would be like if your name was "Anonymous"? You'd get credit for everything nobody wanted credit for...?
