If you have forgotten the Admin PIN code, the only way to reset it to default is to do a hard factory reset. This is the same as the factory reset in the system menu (MENU > SYSTEM > FACTORY RESET).
This erases all settings, including account information and contacts!
- Disconnect the power supply cable. Note that this is the same as the network cable if the phone uses Power over Ethernet (PoE).
- Press and hold the MENU button while you connect the cable again (i.e. start the Avaya B179). Hold the button pressed until the SYSTEM RECOVERY menu is shown on the display.
You can press any other button than 1, 2, or 3 to start the phone without resetting.
- Press 1 to select Reset Configuration and confirm your selection by pressing OK.
- When the phone starts, upgrade to the latest version of the software and re-configure account setup and other settings (see Basic settings for more information).
