Stephen Elop, president of the Microsoft Business Division says that many companies have already bypassed buying an IP PBX box:
"...by using software to do the job that hardware did in the past -- only do it better"
Here is a video of Elop's comments:
Here is a non-Microsoft take on the new features in OCS 2007 R2
Here another blogger says some companies already use OCS as a PBX and has a checklist o see if you company is a fit for an OCS only implementation:
This article claims the release after R2 will be the "PBX replacer" version.
This article claims that OCS R3 will be the "replacer" edition: (see paragraph 7)
My opinion? I think Microsoft's OCS product sure appears to be moving in that direction. Each release has more and more PBX features. With R2 they now have a quite sophisticated operator panel. (perhaps too complicated for the SMB?) They have native OCS phone handsets (http://products.nortel.com/go/product_content.jsp?segId=0&parId=0&prod_id=64241) and SNOM has released an OCS firmware for their very popular SNOM 3XX series to work with OCS.
I think OCS currently does not fit the majority of SMB organizations but it is interesting to watch this unfold.
