Wainhouse research has released the results of a survey that shows Microsoft leads the Unified Communications race at small and large customers (160 end users where asked) -
Survey responses indicate that Microsoft has a commanding lead in the enterprise unified communications space with 48% of those surveyed stating that they are currently using or considering to use Microsoft OCS within their organization as compared to 35% currently using or considering to use Cisco UPC and 24% currently using or considering to use IBM Lotus Sametime.
In line with what we see at customers and partners it also states that "One surprising statistic is the huge mindshare Microsoft has generated over all other unified communications solutions."
Microsoft is not only a genius at marketing, personally I think that Office Communications Server 2007 and the accompanying line of products (See Just how big is the OCS release?) is the most interesting release of products from Microsoft since Exchange 4.0 was shipped more than 11 years ago back in March 1996 (See my blog Microsoft Exchange's 10 year anniversary).
