I was at a conference (UC Summit 2010) a week ago. Microsoft was there and presented OCS. I think this is a new name but it is what it is.
They claim to have 100,000 connections worldwide. Most of those appear to be large multi-national corps.
I've done some research on it since getting back and the documentation is really thin. Much the same for the product -- but it is picking up speed. The versions started with 2005 then 2007 and 2007R2. Version '14' will probably be released this fall as 2010. I couldn't find a beta release and only one article on the upcoming product.
It does not replace the PBX but it has some deep hooks into it.
What does 3CX think of this product?
