Polycom Factory Reset
From KlavoWiki
For the key combination, press and hold certain key combinations (depending on the phone model) simultaneously during the countdown process in the BootROM (or when the phone has been fully booted) until the password prompt appears:
- IP 450, 550, 600, 601, and 650, and 670 and VVX 1500: 4, 6, 8 and * dial pad keys
- IP 32x/33x, 430, 560, 7000: 1, 3, 5, and 7 dial pad keys
- IP 6000: 6, 8 and * 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). Polycom recommends that you change the administrative password from the default value.
Note: As of SIP 3.2.0, users can restart their phones by pressing the Menu key, and then selecting Settings > Basic > Restart Phone. Any new BootROM and SIP applications will be downloaded to the phone as a result of this restart.
