ya you are right. so on the punch-down block (PBX? i hope i'm using the right terminology) all i would need to do is move the 4 wires (looks like 2 blue and 2 orange for each line?) to the new "port", which would change the "address" i see in DB but would maintain the extension and all features.

just trying to make sure i got it before i start pulling up these tiny wires lol.

also, has anyone run into an issue with the current wires being really short, as in they may not reach from one port to another?
