Go into the extension programming and change the line settings to no ring. It is best done if you have a display phone so you can see the changes. If not, then you will need to look at the flashing line lights when you enter the programming mode.
Press Feature 00. This will take you into the programming mode. You should see the line buttons lit up green. They will be Solid (Immediate Ring) or Slow Flash (Delayed Ring) or Fast Flash (No Ring). I assume yours is solid so push each line button until it changes to a fast flash. Once done press Feature 00 to exit the system and save the settings.
