Yeah, ProVision is for Avaya employees only. One function it has is that you can download the entire switch translation to your PC, reconfigure and then upload it back to the switch. Wouldn't that be beautiful to have?! Imagine making switch changes that are business effecting offline and then just uploading them after hours!!
As it was explained to me, Avaya (Lucent at the time) developed the software and did start offering it to the public. But Microsoft stepped in and started to threaten a lawsuit if they did not stop distributing the software because something about it infringed on some Windows copyrights. So a deal was struck that only employees of Avaya could have the software. Chalk another one up for Uncle Bill!!
