New UC hardware
I recently acquired a Jabra GN9350 to be my primary OCS telephony headset, and all I can say is that this is an awesome piece of hardware!
Crystal-clear audio, excellent range (I can walk around my whole apartment, or the whole floor at Microsoft!), and it fully integrates with Office Communicator including answer/hang-up/mute buttons - so I have complete wireless freedom.
Combined with my Communicator Phone Edition for when I want a handset/speakerphone, or if my PC is turned off, this makes for an excellent all-round experience for talking on the phone, taking part in a concall, or presenting in a LiveMeeting!
