IP Phones locked, not registering with CCM 3.3 version
I am currently setting up a Cisco CallManager 3.3 with Cisco 7940 and Cisco 7960 IP phones. I noticed that the phones Network Configuration settings cannot be adjusted. The settings has been locked for all the IP phones I am using. They all have different IP addresses, DHCP addresses, default gateway IP addresses and CallManager IP addresses. I tried changing the IP addresses and other settings, but I cannot do it.
I also noticed a padlock sign on the IP phones while trying to change the settings. I have used the **# combination keys to unlock the IP phones but without success.
Please what do I do? I will appreciate your helps to enable me change the settings I want. Or is it that I am doing somethings I'm not supposed to do which is making all the IP phones to be locked? Thanks a lot.
