I've never connect a XM24 expansion module to a 6424D+ on an IP 500 v2 unit. I'm noticing that when I put a USER appearance on any of the XM24 button, I can use it to dial but it doesn't light up to give an indication that the user is on the phone. When I program the same USER button on any one of the buttons on the 6424D+, it lights up just fine. I've search for all sorts of different 3 pair cable pin-outs and no matter which style I use, the results are the same. I'm using a 1151A1 power supply with this set up ? Am I missing something ? Do the buttons just not light up ? Please advise.
