I have an OCS 2007 R2 implementation running in testing that we are about to move into production. The issue that I have is we have setup the users to SIP with their email addresses. Those with domaina.com work perfect, but those with domainb.com say server is un-available.
I added the SIP domain to the OCS Manager but still no luck. What do I have to do to get it to work? I am using the internal certificate server from my AD versus a 3rd party cert.
