I need to be able to detect dtmf key presses - eg. play a message then ask user to press a '1','2' or '3' ... I'm able to play the message but cant detect any key presses , i'm using a USR sportster voice modem ive tried using a component to detect dtmf (VML - voice modem library by Roman Mochalov.) but i still cant detect any dtmf.
