Configuring Via Keypad - Yealink T22P Manual

Enterprise IP Phone Getting Started
When all accounts register fail, phone will display "No Service" by default.
When the phone reboot, it will register automatically. If many phones register at the
same time, this will affect the server, the users can set the register power up time so
that the phone will random register automatically within the set time.
Setting the power up time via web interface:
Choose Network->Advanced-> Registration random, enter the time in the field.
Note:
Should the IP PBX (SIP registrar) require an authentication, you will be prompted to
enter the correct password. Make sure you are using the appropriate input method or
enter the password via the web user interface.
