Its not really "caller id" that they use, that is a consumer product. They use ANI (Automatic Number Identification), you can't spoof it or block it. You also can't trick them by using a cell phone, ANI reports that as well.
The worst case scenario is that you swap the boxes every few months.
If one of you boxes is "Of Hook" all the time, or otherwise screws up your phones, then the box is bad. If you call customer service and complain just right, they will send you a free or low cost replacement.
There are things that Directv will tell you they don't do, like send you a 5 satellite dish and let you install it yourself. However if you get a supervisor they can make an exception.
