If there are lines through your line appearances than your phone is likely not properly registered with your Callmanager or SIP registrar, you need to configure your phone properly so it registers and associates with an extension on your PBX or hosted service.

can you explain me how is your phone connect to internet.
best on your Question its seems to me you cant hear a dial tone because of following one or more factors might apply
  1. you must log into the Extension Mobility service
  2. you must enter a client matter code (CMC) or forced authorization code (FAC) after dialing a number
  3. your phone has time -of-day restrictions that prevent you from using some features during certain hours of the day

Hope this helps

Using the soft buttons at the bottom of the display, click the last button on the right (More). This will provide another set of options. The third option from the left should say "DND". Press the soft button below this option to turn off DND.
