Names for Extensions and Lines


Extensions and lines can have names instead of just circuit numbers. These names show on a keyset’s display when the user places or answers calls. Extension and line names make it easier to identify callers. The user does not have to refer to a directory when processing calls. Extension and line names can consist of upper and lower case letters, spaces and punctuation, and can be up to 18 characters long.

Conditions and Defaults


  • None.

Default Setting

  • No extension names assigned (the extension’s number displays instead).
  • All line names are LINE followed by the line’s number (e.g., LINE 2).
  • User-entered names are available only at the attendant (Class of Service 1).
