I am trying to reset the admin password for my two polycom VVX500's. The phones came used from another company and we don't have any way to access the admin password. Unfortunately, the new hosted VOIP provider has to access the admin functions to program the phones to their system. I have tried the infamous 4 6 8 * method multiple ways. I have tried it at power up, during application load, and even at the home screen. None of these options have worked. According to Polycom, they won't release the method to fix it because the "resellers" can charge to fix it. We need to get these reprogrammed this weekend because the new system starts next week. Can anyone walk through the admin password reset process step by step?
