Although I do not agree completely with the arguments and conclusions (Gartner notes that the report concern only the given period of time)this report provides good picture and information about UC, Unified Communications field distributions and alliances. You can draw your own conclusions.
Unified communications (UC) offer the ability to significantly improve how individuals, groups and companies interact and perform. UC enables multiple communication channels to be coordinated. In some cases, separate servers may be consolidated, but more frequently, UC adds value to existing communication servers. Key technologies include Internet Protocol (IP)-PBX, voice over IP (VoIP), presence, e-mail, audio and Web conferencing, videoconferencing, voice mail, unified messaging and instant messaging (IM).
Another key capability of UC is that it offers a method to integrate communication functions directly with business applications; Gartner calls this capability "communications-enabled business processes."
The largest single value of UC is its ability to reduce "human latency" in business processes. Although communication methods (such as voice or IM) can be used individually and separately, organizations should examine how bringing these methods together can increase synergies and efficiencies. To accomplish this, companies should review how individuals and groups use communications internally, then undertake pilots and trials that could lead to improved processes. This research reviews relevant technologies and vendor offerings that can assist in these goals.
