I have a Csico 7940 phone with network and sip setting locked. I am trying to do factory reset but common procedure holding # , plugin power cabe, when leds flashing in turn, releasing #, the press 123456789*0# doesn’t work.
Some comments saying using a DHCP sever to provision the TFTP server address and a TFTP sever to load the firmware for recovery. I setup a solarwinds DHCP sever. The phone IP address could be changed to 192.168.0.2, but the TFTP sever address couldn’t. It is always 0.0.0.0 thought I set it 192.168.0.1 in the server conf. Anyone has the experience?
