Starting on idle display, the user can show line statuses using UP or DOWN arrow.
For example, Line Key 2 (defined as private, extension 1, Short Name 9876) show text
Line 2 9876
READY
most of the time.
Unfortunatelly, if no Short Name specified (e.g. Line Key 3 defined as private, extension 1, <Short_Name></ShortName>) then it show
Line 3 <11 blinking chars of garbage here>
READY
It seems that uninitialized pointer is used here in firmware (firmware before 7.5.x shows "READY" text only, no first line at all).
Also, the support for the new, digital, attendant console has been added in 7.5.2b (released July 2012). The "Att.Cons.Preferences" line has been added to main menu. But this text is not localized. Of course - newest avaiable dictionaries are 7.5.1 version. Even English dictionary, which require NO translation is not released for the current version (7.5.3) nor previous version (7.5.2b). Embedded dictionary is part of firmware, but unbundled version is required for volunters to create localized dictionaries.
Well, I can understand that "unsupported language" mean unsupported. But even German dictionaries are unavaiable two months past release of 7.5.2b ...
