The FSF says it is not Free or GPL compatible:

It's definitely neither.  The license requires you to use Polycom's
trademarks in any products you create, and then lets Polycom force you
to make changes if they decide your product isn't worthy of that
This amounts to a restriciton on distribution and modification.  Worse,
you don't know ahead of time what the restriction is -- Polycom can
decide at any time for pretty much any reason that they want to stop
you, and do so.

So much for that idea. :/
