For the past few weeks my team has been using Office Communicator Server 2007.  From my laptop, I can make a telephone call, receive calls, route calls to voice mail or other telephone numbers, ring multiple phones at the same time, hold multi point conference calls and utilize webcams, etc.  All of the whiz bang unified communications offer an interesting array of presence features. See the Quick Reference Card for a good description of the client side view. I particularly like the corporate address book integration.  Instant messaging has taken on a whole new realm, especially with Microsoft RoundTable in the conference room.  That thing is scary good.  It's fun to talk and walk around a table.  Try it!

I am also one of about 75 people in Microsoft with a Windows Mobile 6 Palm Treo 750.  The kewl thing is that it's the build you'll be able to buy from AT&T when they release it.  The fast 3G speeds, improved WM6 interface, and integration with OCS is beyond fascinating.  I'll be doing a side-by-side comparison with my Verizon Motorola Q very soon so stay tuned for that.

Does OCS 2007 sound interesting?  Well, why not take it out for a spin?  Here's the abstract for the download:

Microsoft Office Communicator 2007 introduces a wide range of new features, most notably enhanced presence and enterprise voice capabilities, enabling users to place computer-to-computer calls and to place outbound calls to, and accept incoming calls from, traditional (PBX/PSTN) phone users. Microsoft Office Communicator 2007 also introduces robust call-forwarding features, support for USB audio devices, automatic setup of audio and video devices, and the ability to add Active Directory Domain Services distribution groups to your Communicator Contact List.
