New and Changed Features
Set password on first login
As of Firmware Release 12.0(7)SR2, it's mandatory to set up the passwords before the phone's initial registration (Out-Of-Box) when both the user and admin passwords are empty. It is also required to set up the passwords after a factory reset. Anyone who accesses the phone web page is requested to set passwords for both the administrator and the user during the OOB stage. The passwords must comply with the password rules.
Note |
Sometimes it may be difficult to enter user passwords on a phone since a password may consist of capital letters, small letters, numbers, and special characters. Despite the complex password defined on the phone web interface, a system administrator can provide a simple or even blank password to a user through provisioning as a workaround. |

Update TLS Minimum Value
With Firmware Release 12.0(7)SR2, the default minimum TLS value of the phone is TLS 1.2.
When the phone functions as a client, the legacy option of TLS Min Version is now renamed to TLS Client Min Version. The corresponding XML parameter in the phone configuration file (cfg.xml) is updated to <TLS_Client_Min_Version>.
Note |
If you are working with your own configuration file, the previous <TLS_Min_Version> parameter still works. However, avoid using both <TLS_Client_Min_Version> and <TLS_Min_Version> in the same configuration file. |
When the phone functions as a server, you can control the minimum TLS value with the new TLS Server Min Version option under on the phone administration web page.
