Unified Communications is not a single product and it is not to be confused with unified messaging.
- Unified messaging pulls together messages from several sources such as e-mail, voice mail and faxes and enables an individual to check and archive those messages from different communication devices in one place. In that regard, Google Voice is sort of a unified messaging (UM) system.
- Unified communications adds a real-time component to the UM non-real-time services. Think instant messaging (IM) or videoconferencing (VC) as real-time services. Key to this real-time component is presence and availability—I know where the recipients of my communication efforts are and if they are available.
What's the big deal? Communication is enriched by addressing more senses in human-human interaction, much like in a real-world encounter.
- You can write and talk.
- Read and listen.
- Make gestures and watch facial expressions.
- Have a coordinated and live view of the same documents and objects.
- Minimizing human delays.
