Is there an easy way swap ports for 2 numbers on a Toshiba cix 670? I have no spare slots to move a number to. I'm new to Toshiba, on an Avaya G3r I could "X"-port the PDN eqt no. There does not appear to be that option on the 670. I know this is an elementary question, but my Co. won't give me any training. My apologies.
