This message means that the system does not see a telephone connected to that extension. Check the extension that you are calling to see if it is operational. Check the extension number by using Feature *0 and pressing the intercom button.

I would highly suggest to reset your phone so that the system will be refreshed and you will be able to do any changes on your phone.

Thanks

For external numbers press FEATURE *1, then press the button you want to store the number on, then enter the phone number using the dialpad.
For internal numbers press FEATURE *2, then press the button you want to store the number on, then enter the extension number using the dialpad.
To determine what is currently programmed on a button, press FEATURE *0, then the button to identify and the display will show what feature or autodial number is programmed on the button. If the button is a line button or line pool button, you will not be able to clear it through user level button programming. System level programming must be accessed to change line appearances.

The not in service message is given when there is no telephone attached to the intercom number your trying to call. I'd re-check the intercom number your calling, this can be done by using the button inquiry feature on the set your calling. At the set your calling, press feature *0, then press the intercom button on the lower right hand side of the set. The screen will display the intercom number of the set.

If you plug the telephone into an activated (connected to the Norstar System) telephone jack, the lights should begin to blink while the phone boots-up. The system automatically assigns an extension number. To see what the ext. # assigned to the phone is, press "Feature * 0" (Button Inquiry) and press an intercom button. This will display the ext, # and Set Name of the phone.
Good Luck!
