i knjow this is an old thread but im hoping for an easy fix. i am just a lowly front desk clerk (but former it guy) our phonesuite console (112) all of a sudden will not dial any of the room extensions. It will blink the lights in the room, but not ring. rooms can call 0 and get the front desk, and we can transfer calls to a couple of analog cordless handsets. we have been trying to get tech support out here for over a month (according to my GM) I am convinced it is a simple fix but maybe not. Any help?
