Hello, I have an IP600 running 4612 handsets, everything is setup correctly and I can get the handsets to initalize and load software from tftp etc. The problem occurs after apporx 2 mins on a call when the phone stops (none of the keys work) and shortly after, the speech stops as well. I have tried "pinging" the handset whilst on a call and the ping time stays around 10ms until the phone locks and then it becomes unreachable. The only way to get it working again is to either pull the plug or do the " Hold R E S E T" sequence. does anyone have any ideas?
Thanks
Thanks
