I have several Polycom SPIP331 phones that I am trying to reprovision to our new 3CX system. They are currently provisioned to the test 3CX server I built when evaluating 3CX, and now I cannot get them to refresh their DHCP lease to get the Option 66 that points to the new server. I have tried to access the advanced settings on the phone, but it will not accept the old admin password, the default of 456, nor will it reset to the MAC address as described in all of the things I have found by doing a search on Google. I tried looking at the provisioning template in 3CX, and changing %%DESKPHONE_PASSWORD%% to 12345, but that did not work either. Does anyone know what I am missing?
