I use IIS for our phones to get firmware and settings. We have had 96xx, 961x and B189 models deployed on the same floor and have been able to combine all the relevant firmware into 1 specific folder where the web server points. Recently, we have also started deploying the J169 models. Since adding these files into the mix the 96xx,961x models lose the visiting user field for whatever reason. The only way to get this back is to repoint the webserver at the old folder, without the J169 files. Has anyone come across this?
