I haven't really done anything as I'm not sure what to do. I was going to "Delete Registered IP Phone - 90-23" for my extension and reconfigure it but I get error "There were errors when trying to apply the changes"
The only thing I can identify is that my IP on my computer used to be 192.168.2.177 and because we had to change WEP key on our wireless network all the IP addresses have changed for everyone on the network from what I can see.
our NEC rep is also lost with this...
Actually we had an issue with our phone system beginning of week, it kept looping. Eventually after troubleshooting it looked like the ram stick on the main board was the problem.. so for now until its replaced the stick of ram is missing. I really doubt this would be the problem?

thank you for any help - please let me know if I can elaborate in any other way..
