Hey all, when we make call using mobile phone to exchange, we usually get an automated voice response which prompts us to press certain keys. So my question is how does the automated voice response system know which keys are pressed, if we use sim300CZ to design a automated voice response, how sim300CZ detect a keypress sent by the other side. Anyone knows and can share it? Thanks a lot. Sorry about my English too bad.
