Ok my telemarketer's phone is messed up! I goto his desk, cuz he wanted another barge in line, but when i start to use his phone i realise that nothing works. Pressing buttons doesnt do anything. Its like none of the buttons work. And on the left side there is a ???? where the ext. # should be. He says that he didnt do anything and the phone just stoped working by itself. Any ideas??? It is very important he have a working phone.

Thanks
