This UC520 is working fine before I restart last week. After restarting the system, three of ip phones(7961) are not working. It only show registration at the button of ip phone lcd screen. Today, I reset one of ip phone pressing 1-9*0# after power recycle. After that 1) it shows MAC address of phone 2) ip address of phone, term61.default and upgrading These two processing are keeping on running.
So, I used new ip phone(7940) and plugged in to that switch port. It runs with the following procedure,
Configuring CM List
End up with TFTP Timeout
Even I plugged in the new ip phone to live phone's switch port and did a testing, it also end up with TFTP time out.
I used the debug tftp packet and ephone register but no errors. Any idea?
