All of the vendors are approaching UC from various angles, and enterprises need to figure out which approach makes the most sense for their particular environment. For example, most of the switch vendors view the IP PBX as the starting point for UC capabilities.

Cisco's approach is based on the converged IP network, while IBM views presence as the starting point, and Microsoft sees the desktop as the heart of UC. All of these approaches make sense and have pros and cons, and companies need to determine which fits best with their philosophy.Each month, SearchUnifiedCommunications.com will profile a key UC vendor to help you better understand the company's business model and how it may fit into your UC strategy.
Microsoft
Microsoft's vision for UC brings formerly separate modes or channels of communication and messaging together around a single identity, allowing for streamlined communications for the user and increased operational efficiency for IT. With presence as the backbone, UC makes this set of communications capabilities available from within the business processes and applications that information workers use most.
Microsoft's core UC offerings are Office Communications Server (OCS) 2007 and the Microsoft Office Communicator client (referred to as MOC or Communicator). Microsoft OCS is the evolution of Microsoft Live Communication Server (LCS), adding VoIP/telephony and conferencing capabilities to LCS's enterprise IM and presence features. Office Communications Server 2007 supports federation between organizations using OCS 2007, and with public IM systems (AOL, Yahoo and Windows Live).
Microsoft's enhanced VoIP feature is a software-based solution that lets information workers initiate voice communications from the context of the application from which they are working. OCS 2007 also works with existing enterprise telephony systems (PBX) either natively over SIP or via a media gateway and public switched telephone networks.
Microsoft insists that OCS is not an IP-PBX, but it is expected that OCS will ultimately be used instead of the PBX in some enterprises, although it is currently lacking some of the functions capabilities offered by most enterprise telephony vendors.
