We just installed a used Norstar Phone system and would like to change the Directory Numbers (Extensions) in the system. The book that came with the system doesn't address this.

Is there a code that I can use to change the extension numbers on the phones at each desk?

Thanks so much for your help,

Barbara

Do you mean change the extension length or just change the extension number?

Change the Extension number please.

what is your KSU type and software version?
