I've decided to let the current progress on phpCallCenter be visible before it's released. The UI has taken a turn, in some places I think, for the better. You can view a demo here: http://phpcc.greaterscope.net. Usable accounts (username/password) are:
* Administrator: admin@gs.net/testing
* Employee: second@gs.net/testing
* Employee with Admin rights: tech@gs.net/testing
* Guest: guest@gs.net/testing
Please note: This is an unreleased and unfinished version.
