Polycom only manufactures these phones for our third party partners so any requests like this would need to be answered by Avaya.
I am not aware of any method on how to do so.

I know this has already been answered, but I have had some experience with the 2033 nortel star phone.
You aren't able to change what kind of firmware it's running.
I know with the Nortel 11xx series you can flash them to a SIP firmware from UniStim but the 2033 is too old of a model to support alternate firmwares.
