Anyone have a good cheap/donation I could acquire these Polycom devices IP320,IP321,IP331,IP450,IP4000? Possibly an ip7000 and Soundstation Duo at deeply discounted prices? I've already purchased an IP301, IP430, IP600 and IP601, they should be here friday... if anyone has the above devices and would like to donate/sell cheap for my testing lab please email me off list, I'm trying to round out my Polycom test set so I can begin the process of pushing 4.x for the models that support it and verify that we don't have any weird interactions for the ones left behind in 3.1.8 and 3.2.7 .. Thanks, /b
