Expansion Module

[refram]

Hi. I'm running CallManager 4.3(1) and am using 7975 phones. We are tying to get a 7916 expansion module working on some of them. Can this be done? I'm using service release 1 of CallManager

OK, I did the upgrade (to 4.3(2)...no service packs), but I'm still not seeing the expansion module. I can see the expansion module configuration on the phone within CallManager (and have selected it), but when I look at the phone itself, it says the expansion module is offline. I also can't see the firmware version of the expansion module on the phone itself.
