Question about Cisco 7910 IP Phone
How? I purchased 3 of these Cisco 7940 IP phones online. I thought I could unlock them and load the SIP firmware. No such luck. The suggested **# does nothing. Reboot holding # does nothing. Any help? I've tried everything I could find suggested online.
Unlocking a Cisco 7940
1) Unplug the phone
2) Plug the phone back in while holding the # key
The phone will soon display “Reset key sequence detected”
3) After several lights flash press the following keys in order:
1 2 3 4 5 6 7 8 9 * 0 #
4) The phone will then ask you if you want to save the network configurations:
Save network cfg? 1=yes 2=no
5) The phone will soon display “Factory reset initiated” and will continue
through the boot up process.
If that process fails to work for some reason there
is a second method.
