Does anybody know where I can UC520 4.3 from? I think I've seen it mentioned that this version support extension mobility configuration via the GUI which I need. However, I'm also restricted to version 4.x as I'm integrating with ARC Express which states 4.x must be used. I've not asked if 7.x is supported.
I've looked under http://www.cisco.com/cgi-bin/tablebuild.pl/UC520 and version 4.3 is skipped.
Could I just load the CME 4.3 tar? The UC520 downloads seem to have extra files with UC520 specific labels hence I'm a bit concerned about this aproach.
