We have the GMX-48 phone system. I know it's obsolete, but we need to know how to change the names to correspond with the extentions on the display. We have one of the user's guides but no manual. HELP PLEASE!

1) Move this to the Intertel board and you will get more responses.
2) Get a manual. I believe that is available by clicking on the link at the top of the page.

[DA] for Station Data then [B] for extension and username assignments.

You need the system programming not the users programming.

moved to the Intertel section.
