It's also one of those things that if two employees swap places, swapping their phones in the process---then don't realize that the extensions don't swap with the phones. They jump in and try to access their mailbox and ---bam---4 strikes and they're out.

You've got to impress upon your customers to let you know when any changes are taking place--you can then tell them what to watch out for---and also that you need to go there possibly to switch jumpers. If they don't, then the lock-outs are inevitable. It's their call.

One of the things I insist on is to program names for each extension. Sometimes the employees don't even know their extension number, but if they see that when they intercom someone, it's the "wrong" name. Sometimes it alerts them to the fact that "something is wrong".
