Hey, you are good. Don't know why I didn't think of that. So... it shows as x173 instead of 180 - I'll figure out why the station assignment didn't match... but interestingly it still doesn't "ring". Just silently sits there with its little green lights blinking instead of a ring tone. I'm clueless about the ring generator but I know I do have one setup on the dxp plus... but does it have to be wired into the individual extension somehow? Do you know of any way to acquire the VMMI if you are an owner of the comdial dxp plus? These things are so old now, they ought to lighten up on the license restrictions.
