The solution was far too expensive, which is why we ended up moving to a new vendor. The solution had slow connections and very bad routers. We continuously had issues with the VPN and proxy configuration. AT&T could simplify its user interface and log on. Typically, where you log on is independent of the solution, as long as you have had authorization. With this solution, you needed to configure a single entry point which wasn't ideal. The solution should have been able to integrate more easily with Microsoft.
