If you look towards the bottom of this page:
http://downloads.polycom.com/voice/voip/sip_sw_releases_matrix.html
it says the following:
Yes - This platform was supported on the release
No - This platform was supported on the release
Beta - This release was available for Beta test purposes only; Beta releases are not supported beyond the Beta trial period.
so what's the difference between YES or NO?
And when it means the platform was or wasn't supported (as I'm assuming that's what you mean), does that mean that no features were added in that release, or it's really not supported on that phone?
