I have read that there is a 32-bit version availble for testing. Where do I get this? I have Exchange 2007 64 bit and it is running on a 64 bit server, but my lab computers for testing are only 32 bit. I want to experiment with integrating Unified Messaging with a Cisco uc520 without messing up or causeing downtime on my exchange server.
