A bank board room in L.A. area is going to have a huge conference room table. The execs mentioned that they get "crumpled paper noise" syndrome with their current voice (looked like a Polycom Soundstation-like)instrument. They asked me about wireless (ceiling) microphones for their conference room and I thought about using these. But they go on the table, not in the ceiling?

Any suggestions? It's an Avaya hybrid VoIP phone system.
