Anybody have tested the voice capacity of AP650 802.11n  @ 40 Mhz  using a G.711 codec? There was a presentation before that an AP7131 capacity in a real world scenario was 30 calls.  Does this still  hold true for the AP650 also?    The reason I am asking because we have a call center customer who is planning to put  802.11n wireless PCI cards on all the 300 desktops  located in one big room.  Each PC desktop will be using softphones for voice and simultaneously for web data applications.  There is no mobility involve and they are expecting  100% voice utilization. Any help would be appreciated.
