Hello fyrd,
welcome to the Polycom Community.
Usually you should work with a qualified Polycom Reseller as any advise without knowing the layout of the room is a tricky one to make.
Is this a analog Line or a SIP Installation?
We have plenty of different Conference Phones in the SoundStation range that offer external Microphone connections to suit larger meeting rooms and are full duplex in order to suit a conference setup.
Best Regards
Steffen Baier
