I have a 7200 with 4.75. Three of the 5220 phones have 64 button AOM's. The consoles stop working about twice a week. They have to unplug the LAN cable to reset.

The 5220 is powered by a POE switch in the IT room. I though of putting the phones on their own power-supply's and getting them off the 48 port POE switch to see if something network related was causing the modules to stop working.

Has anyone seen this?
Thanks
