Has anyone here implemented Authorization Codes? I'm thinking about setting this up in my system. I know how to activate the feature, but was wondering if any of you ran into any unexpected problems. I want to restrict all long distance calls from all phones, unless you have an authorization code. Should I let users choose their own code or should I create the codes for them? Should I give the helpdesk access to change and reset these codes? I certainly don't want to do it. This will be a company wide change that will effect a few thousand employees, so I want to make sure I don't screw it up.
