psnyder1985,
One of the main things with the Polycom, is that it is always assumed that you will be using provisioning files to provision the Polycom.
As such, many of the advanced features of the Polycom can not be set via the Web interface of the phone, they have to be done via the provisioning files..in XML format. It appears that you can disable them this way as well...
The following may be of help to you....while not a step by step, it should provide some direction.
