Guys,
The reason I put the phone swap feature as second is because the phones may not be the same style and then you are not able to swap them; I have seen customers try this. Even if they are you need to make sure they take their phone with them to make sure the same amount of buttons are involved; as well as the labeling. A basic and executive phone will swap, but the basic won't show all of the keys or even have a display for that matter.
I look at it this way, most customers have no idea what is really going on with their phone system or how it work; that is why we exist. If we provide blanket statements then it will most likely work for most things, but not all, and that is where you get caught.
Even swapping the cross connects will have the same issue as a phone swap feature if they don't move the phones around, but the guy doing the cross connect swap should know to do that; unless it is the customer.
My worst nightmare is a customer with tools and an over abundant sense of capability mixed with a complete lack of understanding or misinformation. It makes me shudder to even think about it.
Thanks,
TE
