In my last post, I mentioned that the lack of standards and platform interoperability was one of the biggest issues for early adopters of Unified Communications technologies. Microsoft and IBM are two of the biggest players in the Unified Communications arena. Microsoft is aggressively pushing for its share of the Unified Communications pie with their UCC (Unified Communications & Collaboration) tools. IBM, with their Lotus Sametime product, recently announced that they are investing $1 billion in R&D and acquisitions to strengthen their Unified Communications position. However, there are reports that an impromptu discussion at a VoiceCon Orlando session may lead to the two titans working on testing the interoperability of their products. If they manage to organize the testing, a demonstration of the interoperability may be performed at VoiceCon San Francisco this Fall.
