Negetive. 568A will give you USOC 2 line compatability. 568B you would have to put the 2 line on the green pair. Patch panels are totally inefficient for voice 1 pair cabling. 110 or my preference 66 blocks utilize voice cable WAY more efficiently. Cat5e will cut you voice loop limit down considerably on long runs. While small jobs are great for all patch panels...large jobs it's totally ineffective and tail chasing every time you need to add a voice jack in a location.
