Can dial from soft phone, can't dial from analogic phone

Hi, as the title says, i can very well place a call from any soft phone (X-lite) to any other soft phone or to the analogic phone, but when i try to place a call from the analogic phone, all i hear the tone. even if i push a number to call any other extension i still have a tone and nothing elce. Any ideea why ?
