I am installing a G250-DCP on a CM 3.1.1 with an S8300 and two G700 gateways. I configured the G250 and put it on the network and everything seemed to be fine. I then programmed four 2420 phones on the gateway and hooked them up. After testing the G250 I have found that 6 of the ports on the integrated dcp work fine and 6 of the ports have an erratic display operation. At times garbage and misspellings come on the display when you touch a button. All the audio seems to function fine on all ports just the displays on 6 of the 12 ports are acting weird. There are no alarms on the system at all. I reset the system, no help. Then I tried a new G250-DCP gateway and it is doing the exact same thing. Does anyone have any ideas ??
