I have now been able to look at the PC which is running the OS2 Version of AVT Phone Express Entree Version 4.03b.
Below is a link to the screens I have been able to access ( px1-s.jpg to px3-s.jpg ) and one of the screens I would like to access ( px4-s.jpg )
https://www.datalogistix.net/voicemail/pxentree.htm I have located a PhoneXpress Entree Version 4.0 System Administrators Guide which says I am suppose to be able to use Function Keys F5 and F6 but I can't get them to do anything.
I am trying to add new mailboxes as indicated in Chapter 3 of the Manual Creating Basic Applications - Creating a Subscriber Mailbox - Manual Page 3-3 (PDF Manual Page 35 )
https://www.datalogistix.net/voicemail/AdminGuide.pdf I can get the mailbox screen to appear as in my posted image 3 ( px3-s.jpg ) but no matter what mailbox number I enter I am told it either is invalid or does not exist. Even known mailboxes.
How does one access their admin menus?
