Open Source - How to reset Polycom phones to factory device settings

Restoring Factory Defaults:

To restore using the keypad, press and hold certain key combinations (depending on the phone model) simultaneously during the countdown process on the screen until the password prompt appears:

• IP 301, 501, 550, 600, 601, and 650, and 670: 4, 6, 8 and * dial pad keys

• IP 450, 320, 330, and 430, 560, 7000: 1, 3, 5, and 7 dial pad keys

Enter the administrator password to initiate the reset. Resetting to factory defaults will also reset the administrator password (factory default password is 456).
