Can anyone tell me if it is possible to terminate all 4 pairs of a CAT-5 wire cross connected on a block to a TN2224B circuit pack into 4 seperate jacks and use each one for a Callmaster V? I have 4 runs going to a room that I need to add 16 phones to... Trying to avoid more cable runs if possible. Just concerned about the shielding of these pairs etc.
