What happens when someone plugs in a GB device or a POE device into a ethernet network wired incorrectly.
In this case, nothing other than dropping that node and any other it's connected to to 100 megabit. Nothing detrimental will occur as both ends of the cables pin 7 and 8 will be broken out. So unless they need gigabit interconnectivity between this node or even more doubtfully a gigabit connection to the WAN, this is the way to go; using pair 4 for the telephone.
