There are no characters on my LCD display, there is no dial tone. Basically the phone is dead.

The IP phone receives its power from the network jack. Verify that the jack (labelled 10/100SW) on the phone is plugged into the network outlet in the wall. Unplug and re-plug the phone into the network jack. Watch the MUTE button on the phone carefully - it should flash (red) 10 seconds after you plug in the phone. If the light does not flash, and nothing comes up on the phone, it is likely that either the phone, the patch cable, or the port is faulty. Check the cables that run into your computer from the phone and/or from your phone to the network jack. Try replacing the cable (you can borrow one from a neighbour for the purposes of this test). Also, try testing the computer in the network jack without connecting to the phone. One more thing to try ... take your phone to another room and plug it into their IP phone network jack. If this works, your network jack is dead. Make sure you communicate this when you call the Telephone Help Desk (Ext. 74663).
