Summary: This unit is very well built. It looks and feels like a high end business desktop phone and works perfectly with the Lync 2010 & 2013 Client. If you have any users (especially older) on the fence about switching to a soft phone client, this is the perfect solution.
Summary: Just received the CX300 and am really glad I went this route. Setup was a breeze - Win 7 recognized it right away and it automatically was set as my default Audio option in Lync. Oh yeah - that's the best, this OCS 2007 phone is forward compatible with Lync 2010 - no firmware updates required, just works out of the box. Sound quality has been great - on both ends. This is a great phone for anyone that works at home in a fully integrated UC environment.
Summary: Intregrates seamlessly with my company's Microsoft Lync solution. I get excellent audio from Egypt to the states even when I'm connected via VPN. The one negative is the lack of a wireless reciever to go with it.
Summary: The device is a must have for home office/office environments. The speaker phone is great. I can plug my Jabra head set into. The device integrates flawlessly into Lync and has been a very welcome addition. I would highly recommend it.
