I am trying to setup OCS Standard Edition here at my school district and seem to have gotten through most of my initial problems but am now at a loss. I have everything setup and running and can log in just fine with OC but when I try to send a message to someone it never goes through. So I ran the Front End validation and I received a Two Party IM error as follows:
Received a failure SIP response: User sip:test2@contoso.com @ Server OCSServer.contoso.com
Received a failure SIP response: [

I'm not sure how to proceed any information would be greatly appreciated. Some background information there is just one server hosting OCS there is no federation, no phone usage routes this is just supposed to host IM throughout my school district.
